Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

This second edition cancels and replaces the first edition (ISO 233-3:1999), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— Added missing diacritical signs to the tables and corrected some errors elsewhere in the text. Added
distinction in transliteration between ا and آ. Changed transliteration of خ (table 1, row 9) and ض
(table 1, row 18), from ḵ to x and ż to z̤ respectively. Changed transliteration of tanvin (table 3, row
2) from ″ to ã.
— Incorporated options for 3 “levels” of transliteration: strict, i.e. fully reversible (with and without
vowels); and a modified but not fully reversible system, which, for example, distinguishes in
transliteration when the characters و and ى function as long vowels or as consonants, and, in the
case of ى, other functions of the character.
— Added hexadecimal character codes (ISO/IEC 10646 or Unicode) to all tables containing Persian
characters and transliterations and therefore omitted Annexes B and D, Annex C thus becoming
Annex B.
— Added Terms and definitions section.

Introduction
This part of ISO 233 is one of a series of International Standards, dealing with the conversion of
systems of writing. The aim of this part of ISO 233 and others in the series is to provide a means for
international communication of written messages in a form which permits the automatic transmission
and reconstitution of these, by men or machines. The system of conversion, in this case, must be
univocal and entirely reversible to allow for retransliteration.
This means that consideration to phonetic and aesthetic matters or to certain national customs is not a
priority: all these considerations are, indeed, ignored by the machine performing the function.
This part of ISO 233 may be used by anyone who has a clear understanding of the system and is certain
that it can be applied without ambiguity. The result obtained will not give a correct pronunciation of
the original text in a person’s own language, but it will serve as a means of finding automatically the
original graphism and thus allow anyone who has knowledge of the original language to pronounce it
correctly. Similarly, one can only pronounce correctly a text written in, for example, English or Polish, if
one has a knowledge of English or Polish.
The existence in Perso-Arabic script of short vowels and other diacritical marks, which are pronounced
but often not written somewhat complicates this reading of the text but as those with knowledge of the
language can read and mentally fill in the missing signs/sounds when reading the original script, so
they can with the transliterated version, e.g. the word پِدَر, which consists of 3 consonants and 2 short
vowels (transliteration: pedar) when written without short vowels would be پدر (transliteration: pdr).
To address the issue of short vowels and other signs that are unwritten, and the fact that some
characters perform more than one function (e.g. characters that can function as either a vowel or a
consonant), ISO 233-3 incorporates three levels: strict and fully reversible, univocal, with short vowels
only transliterated if written in the source text; strict and fully reversible, univocal, with short vowels
included for clarity, regardless of their presence or absence in the source text; and a modified version
of the system that while not fully reversible includes the short vowels and takes account of the different
functions performed by some characters (see 4.1 and 4.2 for further details).
The adoption of this part of ISO 233 for international communication leaves every country free to
adopt for its own use a national standard which may be different, on condition that it is compatible
with this part of ISO 233. The system proposed herein should make this possible and be acceptable to
international use if the graphisms it creates are such that they may be converted automatically into the
graphisms used in any strict national systems.
The adoption of national standards compatible with this part of ISO 233 will permit the representation,
in an international publication, of the morphemes of each language according to the customs of the
country where it is spoken. It will be possible to simplify this representation in order to take into
account the number of the character sets available on different kinds of machines.

Information and documentation — Transliteration of
Arabic characters into Latin characters —
Part 3:
Persian language — Transliteration
1 Scope
This part of ISO 233 establishes a system for the transliteration into Latin characters of the Arabic
characters (often called Perso-Arabic script) used to write the Persian language. This simplification
of the stringent rules established by ISO 233:1984 is especially intended to facilitate the processing of
bibliographic information (e.g. catalogues, indices, citations, etc.).
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute
provisions of this part of ISO 233. For dated references, subsequent amendments to, or revisions of,
any of these publications do not apply. However, parties to agreements based on this part of ISO 233
are encouraged to investigate the possibility of applying the most recent editions of the normative
documents indicated below. For undated references, the latest edition of the normative document
referred to applies. Members of ISO and IEC maintain registers of currently valid International
Standards.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at https:// www .electropedia .org/
3.1
character
element of an alphabetical or other type of writing system that graphically represents a phoneme,
a syllable, a word or even a prosodical characteristic of a given language; it is used either alone
(for example, a letter, a syllabic sign, an ideographical character, a digit, a punctuation mark) or in
combination (such as an accent or a diacritical mark)
Note 1 to entry: A letter having an accent or a diacritical mark, for example â, è, ö, is therefore a character in the
same way as a basic letter.
3.2
vowel
a speech sound produced by unobstructed flow of air through the mouth

3.3
consonant
a speech sound produced by complete or partial closure of the vocal tract
3.4
transliteration
process which consists of representing the characters (3.1) of an alphabetical or syllabic system of
writing by the characters of a conversion alphabet
3.5
retransliteration
process whereby the characters (3.1) of a conversion alphabet are transformed back into those of the
converted writing system
3.6
transcription
process whereby the sounds of a given language are noted by the system of signs of a conversion
language
3.7
romanization
conversion of non-Latin writing systems to the Latin alphabet
4 Transliteration tables
“Hex” in the following tables refers to hexadecimal character codes in the standard ISO/IEC 10646
(Unicode).

4.1 Table 1 — Consonants
The shaded rows, numbered 1b, 30c etc., provide for option three described above, a modified but not
fully-reversible transliteration. They reference the use of consonant characters as vowels (see also
4.2 vowels). Where full reversibility is required only the main numbered rows should be used and the
shaded rows ignored.

* The alif maqsurah is a feature of loan words and names of Arabic origin. It should have a different
Unicode encoding (0649) but in appearance it looks the same as the Persian ye (06CC) and the latter is
likely to occur in actual usage.
Different position forms of Persian characters (initial, medial, final and separate) are shown in Annex A.

4.2 Vowels
Generally, Persian words are written without short vowel signs. However, as the change of vowel sign
can bring about a different meaning (for example: پَر par = feather; پُر por = full), vowel signs may be
used intentionally whenever a difference in meaning is to be emphasized. In tables 2a and 3, both cases
are represented. However, often both the aforementioned examples will be written پر, transliterated

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 233-3:2022(E)

Information and documentation — Transliteration of Arabic
characters into Latin characters —
Part 3:
Persian language — Transliteration
1 Scope
This document establishes a system for the transliteration into Latin characters of the Arabic characters
(often called Perso-Arabic script) used to write the Persian language. This modification of the stringent
rules established by ISO 233:1984 is especially intended to facilitate the processing of bibliographic
information (e.g. catalogues, indices, citations, etc.).
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.
ISO/IEC 10646, Information technology — Universal Character Setcoded character set (UCS)
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply. Additionally, general
principles of conversion of writing systems are given in Annex B.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:

3.1
character
element of an alphabetical or other type of writing system that graphically represents a phoneme, a
syllable, a word or even a prosodical characteristic of a given language; it
Note 1 to entry: It is used either alone (for example, a letter, a syllabic sign, an ideographical character, a digit, a
punctuation mark) or in combination (such as an accent or a diacritical mark)
Note 12 to entry: A letter having an accent or a diacritical mark, for example â, è, ö, is therefore a character in the
same way as a basic letter.

ISO/FDIS 233-3:2022(E)
vowel
speech sound produced by unobstructed flow of air through the mouth

3.3
consonant
speech sound produced by complete or partial closure of the vocal tract

3.4
transliteration
process which consists of representing the characters (3.1)(3.1) of an alphabetical or syllabic system of
writing by the characters of a conversion alphabet

3.5
retransliteration
process whereby the characters (3.1)(3.1) of a conversion alphabet are transformed back into those of
the converted writing system

3.6
transcription
process whereby the sounds of a given language are noted by the system of signs of a conversion
language

3.7
romanization
conversion of non-Latin writing systems to the Latin alphabet
4 Strict Transliterationtransliteration
4.1 General
4.1.1 “Hex” values in the following tables shall be interpreted as character codes in ISO/IEC 10646
(Universal Character Set).
4.1.2 The strict transliteration is intended to be a one-to-one reversible transliteration system
allowing for a simple rule-based machine transliteration.
4.1.3 Persian script does not distinguish between upper and lower case. In Latin script, Persian
names may be written using upper or lower case according to the conventions of the target language.
This is optional. Capitalization rules are not part of this document. A system transliterating from Latin
into Persian script shall therefore be case insensitive. Some of the characters, both Latin and Persian,
have canonical decompositions in Unicode. Any transliteration system should treat precomposed and
decomposed characters equally on input.

  For transliteration of alef madde see 4.3;4.3; and for hamze see 4.5.4.5. Initial alef may function as the bearer of a short
vowel (see 4.3)4.3) or a hamze. In the strict transliteration alef is always transliterated as ‘ā’, hence alef carrying the short
vowel pīš ( ُ◌ 126T) would be transliterated as ‘āo’. For example, the name ﺪﯿﻣا would be ‘āomyd’ according to this system, or, if the
short vowel was unwritten, ‘āmyd’.
b
  Implementations may encounter a single left quotation mark (hex 2018) in existing text.

  Implementations may encounter the Arabic yeh (hex 064A) in existing text.
d
  Alef maqṣūre (Arabic hex 0649) is a feature of loan words and names of Arabic origin. In Persian it is usually written as ی
(hex 06CC) or, for clarity, ٰی (hex 06CC+0670). In the strict transliteration the latter variant is transliterated ‘ý’ (hex 00FD).
e
  For the transliteration of hamze see 4.5


4.44.3 Vowels
4.3.1 Generally, Persian words are written without diacritical vowel signs. However, as the change of
vowel sign can bring about a different meaning (for example: ﺮَﭘ par = feather; ﺮُﭘ por = full), vowel signs
may be used intentionally whenever a difference in meaning is to be emphasized. In Table 2Table 2 and
Table 3,Table 3, both cases are represented. However, often both the aforementioned examples will be
often written ﺮﭘ, transliterated ‘pr’ in the strict univocal system. In transliteration, the diacritical vowel

can be included to clarify the meaning. This would then of course be included in the Perso-Arabic script
if the word were to be reverse transliterated.

4.64.4 Arabic elements in the Persian language
4.4.1 Persian contains many loan words from Arabic. Arabic elements occurring in Persian texts are
treated as follows. Where an Arabic element is not mentioned in this document, ISO 233-1 should be
followed.
4.4.2 As with the diacritical vowel markings, these signs, of Arabic origin, are often not written in
Persian script, usually being used only when a difference in meaning is to be emphasized.

4.4.3 Tāʼ marbūṭaẗ is not part of the Persian language. Where it occurs on an Arabic word found in a
Persian text, it should be treated according to ISO 233 Arabic transliteration: ة (hex 0629) should be
transliterated as ẗ (hex 1E97).
4.4.4 The Arabic word for God (ﷲ, hex 0627, 0644, 0644, 0651, 0670, 0647) should be transliterated
as Allāh.
4.74.5 Hamze
Hamze ( ء ) is not regarded as a character of the Persian alphabet, but as a diacritical mark, and as such
is not always expressed in writing. In fully-pointed words, however, it appears in several graphic forms,
standing alone or written in conjunction with alef ( أ ), vāv ( ؤ ) and ye ( ئ ). In strict, fully-reversible
transliteration, hamze should be transliterated with apostrophe ( ʼ ) and the character bearing it is
transliterated according to Table 4.

  Implementations may encounter a single right quotation mark (hex 2019) in existing text.
4.84.6 Persian relational suffix (ez̤āfe)
4.6.1 In Persian script, after a consonant, including ye ( ی ), ez̤āfe is properly expressed by zīr ( ُ◌ ِ◌ ),
though this is usually not written; e.g.,for example, ﺪﻧوﺎﻣد ِهﻮﻛ → kvhe dmāvnd; ﯽﻨﯿﺳ◌ِ ﻞطا → synye ṭlā; یرﻮﻗ◌ِ
چﯽﻨﯾ → qvrye čyny. In the strict transliteration system, the zīr-e ez̤āfe should be treated as the vowel zīr
when occurring after a final consonant (see Table 2)74TTable 274T) and be transliterated as ‘e’.
4.6.2 After final alef ( ا ) or vāv ( و ), ez̤āfe is marked with ye ( ی ). In the strict transliteration system,
this is treated as any other ye ( ی ) and transliterated as ‘y’ (see Table 1,Table 1, row 32).
4.6.3 After silent he, ez̤āfe is sometimes expressed by writing a diacritical mark over the character
(see Table 5).Table 5). In the strict transliteration system, these cases are transliterated as hʼ. E.g.For
example, ﺶﺳﺮﭘ ﮫﻧﺎﺸﻧ → nšānhʼ prsš; هﺮﺒﻘﻣ◌ٴ بﯽﻧﺎﺘﺳا → mqbrhʼ bāstāny.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not

This document was prepared by Technical Committee ISO/TC 46, Information and documentation.
This second edition cancels and replaces the first edition (ISO 233-3:1999), which has been technically
revised.
The main changes compared to the previous edition are as follows.
— Incorporated options for 3 “levels” of transliteration: strict, i.e. fully reversible (with and without
vowels and other diacritical marks); and a modified but not fully reversible system, which, for
example, distinguishes in transliteration when the characters و and ى function as vowels or as
consonants, and, in the case of ى, other functions of the character.
— Added missing diacritical signs to the tables and corrected some errors elsewhere in the text. Added
distinction in transliteration between ا and آ. Changed transliteration of خ (Table 1, row 9) from ‘ḵ’ to
‘x’. Changed transliteration of ض (Table 1, row 18) from ‘ż’ to ‘z̤’. Changed transliteration of tanvīn
(Table 3, row 2) from ´´ to ã/ẽ/õ.
— Added notes explaining certain grammatical points; updated examples.
— Added hexadecimal character codes (ISO/IEC 10646 or Unicode) to all tables containing Persian
characters and transliterations and therefore omitted Annexes B and D, Annex C thus becoming
Annex B.
— Added the mandatory Terms and definitions clause and renumbered the subsequent clauses.

ISO/FDIS 233-3:2022(E)
Introduction
This document is one of a series of International Standards, dealing with the conversion of systems of
writing. The aim of the ISO 233 series is to provide a means for international communication of written
messages in a form which permits the automatic transmission and reconstitution of these, by humans
or machines. The system of conversion, in this case, must be univocal and entirely reversible to allow
for retransliteration.
This means that consideration to phonetic and aesthetic matters or to certain national customs is not a
priority: all these considerations are, indeed, ignored by the machine performing the function.
This document can be used by anyone who has a clear understanding of the system and is certain
that it can be applied without ambiguity. The result obtained will not give a correct pronunciation of
the original text in a person’s own language, but it will serve as a means of finding automatically the
original graphism, and thus allow anyone who has knowledge of the original language to pronounce it
correctly. Similarly, one can only pronounce correctly a text written in, for example, English or Polish, if
one has a knowledge of English or Polish.
The existence in Perso-Arabic script of vowel signs and other diacritical marks, which are pronounced
but often not written somewhat complicates reading of the text, but as those with knowledge of the
language can read and mentally fill in the missing signs/sounds when reading the original script, so
can they with the transliterated version, for example, the word سِپَر, which consists of 3 consonants
and 2 diacritical vowel signs (transliteration: separ) when written without vowel signs would be سپر
(transliteration: spr).
To address the issue of diacritical vowels and other signs that are unwritten, and the fact that some
characters perform more than one function (e.g. characters that can function as either a vowel or a
consonant), this document incorporates three levels of transliteration:
1) strict and fully reversible, univocal, with diacritical vowels and other signs only transliterated if
written in the source text;
2) strict and fully reversible, univocal, with diacritical vowels and other signs included for clarity,
regardless of their presence or absence in the source text;
3) a modified version of the system that while not fully reversible includes the diacritical vowels and
other signs and takes account of the different functions performed by some characters (see 4.1 and
5.1 for further details).
The adoption of this document for international communication leaves every country free to adopt for
its own use a national standard which can be different, on condition that it is compatible with this
document. The system proposed herein will make this possible and be acceptable to international use if
the graphisms it creates are such that they can be converted automatically into the graphisms used in
any strict national systems.
The adoption of national standards compatible with this document permits the representation, in an
international publication, of the morphemes of each language according to the customs of the country
where it is spoken. It is possible to simplify this representation in order to take into account the number
of the character sets available on different kinds of machines.

Information and documentation — Transliteration of
Arabic characters into Latin characters —
Part 3:
Persian language — Transliteration
1 Scope
This document establishes a system for the transliteration into Latin characters of the Arabic characters
(often called Perso-Arabic script) used to write the Persian language. This modification of the stringent
rules established by ISO 233:1984 is especially intended to facilitate the processing of bibliographic
information (e.g. catalogues, indices, citations, etc.).
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

3.1
character
element of an alphabetical or other type of writing system that graphically represents a phoneme, a
syllable, a word or even a prosodical characteristic of a given language
Note 1 to entry: It is used either alone (for example, a letter, a syllabic sign, an ideographical character, a digit, a
punctuation mark) or in combination (such as an accent or a diacritical mark)
Note 2 to entry: A letter having an accent or a diacritical mark, for example â, è, ö, is therefore a character in the
same way as a basic letter.
3.2
vowel
speech sound produced by unobstructed flow of air through the mouth

4 Strict transliteration
4.1 General
4.1.1 “Hex” values in the following tables shall be interpreted as character codes in ISO/IEC 10646
(Universal Character Set).
4.1.2 The strict transliteration is intended to be a one-to-one reversible transliteration system
allowing for a simple rule-based machine transliteration.
4.1.3 Persian script does not distinguish between upper and lower case. In Latin script, Persian
names may be written using upper or lower case according to the conventions of the target language.
This is optional. Capitalization rules are not part of this document. A system transliterating from Latin
into Persian script shall therefore be case insensitive. Some of the characters, both Latin and Persian,
have canonical decompositions in Unicode. Any transliteration system should treat precomposed and
decomposed characters equally on input.
4.2 Consonants
4.2.1 For a fully reversible transliteration, Table 1 should be used with Table 2 for any vowels included
in the original text.

For transliteration of alef madde see 4.3; and for hamze see 4.5. Initial alef may function as the bearer of a short vowel
(see 4.3) or a hamze. In the strict transliteration alef is always transliterated as ‘ā’, hence alef carrying the short vowel pīš
( ُ◌ ) would be transliterated as ‘āo’. For example, the name ديما would be ‘āomyd’ according to this system, or, if the short
vowel was unwritten, ‘āmyd’.
b
Implementations may encounter a single left quotation mark (hex 2018) in existing text.
c
Implementations may encounter the Arabic yeh (hex 064A) in existing text.
d
Alef maqṣūre (Arabic hex 0649) is a feature of loan words and names of Arabic origin. In Persian it is usually written
as ی (hex 06CC) or, for clarity, یٰ (hex 06CC+0670). In the strict transliteration the latter variant is transliterated ‘ý’ (hex
00FD).

For the transliteration of hamze see 4.5

4.3 Vowels
4.3.1 Generally, Persian words are written without diacritical vowel signs. However, as the change of
vowel sign can bring about a different meaning (for example: رپ par = feather; رُپ por = full), vowel signs َ
may be used intentionally whenever a difference in meaning is to be emphasized. In Table 2 and Table 3,
both cases are represented. However, both the aforementioned examples will be often written رپ,
transliterated ‘pr’ in the strict univocal system. In transliteration, the diacritical vowel can be included
to clarify the meaning. This would then of course be included in the Perso-Arabic script if the word
were to be reverse transliterated.

4.4 Arabic elements in the Persian language
4.4.1 Persian contains many loan words from Arabic. Arabic elements occurring in Persian texts are
treated as follows. Where an Arabic element is not mentioned in this document, ISO 233-1 should be
followed.
4.4.2 As with the diacritical vowel markings, these signs, of Arabic origin, are often not written in
Persian script, usually being used only when a difference in meaning is to be emphasized.
