Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical activity.
ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations,
governmental and non-governmental, in liaison with ISO and IEC, also take part in the work.
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 document 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 or www.iec.ch/members_experts/refdocs).
ISO and IEC draw attention to the possibility that the implementation of this document may involve the
use of (a) patent(s). ISO and IEC take no position concerning the evidence, validity or applicability of any
claimed patent rights in respect thereof. As of the date of publication of this document, ISO and IEC had not
received notice of (a) patent(s) which may be required to implement this document. However, implementers
are cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents and https://patents.iec.ch. ISO and IEC shall not be held
responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not

This document was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 35, User interfaces.
This fourth edition cancels and replaces the third edition (ISO/IEC 9995-3:2010), which has been technically
revised.
The main changes are as follows:
— update of the title;
— revision of Clause 5 (now Clause 4) by a new specification of a “Latin International keyboard layout”;
— removal of Clause 6.
A list of all parts in the ISO/IEC 9995 series can be found on the ISO and IEC websites.

Introduction
Besides demonstrating the details specified in the ISO/IEC 9995 series on an actual keyboard layout, the
Latin International keyboard layout standardized in this document is intended to fulfil the following goals:
— All names (personal and organizational) and texts written in official main languages of all countries can
be entered correctly (provided they use the Latin script).
— For common non-Latin scripts, the common transliteration systems are supported, such as for Arabic,
Chinese (Pinyin), Hebrew, Russian and other languages with Cyrillic script, and Sanskrit.
— Common diacritical marks can be entered by the “dead key” method, which is common for European
layouts. Sequences of two dead keys are used to enter characters with two diacritical marks (as are
needed e.g. for Vietnamese).
— All characters used in “good typography” can be entered easily. Especially, the “comma-shaped
apostrophe” gets a prominent position, while being doubled as “closing single quote” which is allocated
systematically with the other quote characters.
— The Latin script variants Fraktur (Blackletter) and Gaelic, which have some contemporary use despite
their “old fashioned” look, are supported (for environments which provide appropriate fonts and
automatic ligating for Fraktur, which can be controlled by the “zero width non-joiner”).
— Symbols used commonly in business texts are provided, like ¥, ®, or ⌀ (diameter).
— All characters which can be entered are presented on the keytops using the keytop surface efficiently.
— The layout is designed as an extension of the widespread “QWERTY” layout as specified in the US-
American standard ANSI INCITS X3.154-1988. Thus, anybody familiar with its use can continue to use
it without having to learn new things, especially when touch-typing. They only have to learn new key
combinations for the “new” characters which they in fact want to use which were not on the “ANSI”
layout. Also, it is compatible with extensions of that ANSI layout which allocate the Euro symbol (€) on
the level 3 on the “digit 5” key, which are in use e.g. in the Netherlands.
Some detailed design considerations leading to the layout defined in this document are compiled in Annex A.

4 Latin International keyboard layout
4.1 General
The specification presented here for the keyboard layout “Latin International” shall be in accordance with
Table 1, which combines a primary group layout and a secondary group layout, complemented with the
following requests for specific key combinations:

© ISO/IEC 2026 – All rights reserved
— The key combination Level 3 select + “f” shall act as Extra selector (Group 2 single select).
— The key combination Level 3 select + “g” should act as Superselect key combination as defined in ISO/
IEC 9995-9, employing at least Single-selection conformance as defined in the subclause 4.2.2 of ISO/IEC
9995-9:2026.
— The key combination Level 3 select + “q” should either act as an IPA input key defined in subclause 9.3 of
ISO/IEC 9995-9:2026 titled “Entering IPA characters with a special function key”, or it should invoke the
special mode “IPA” as defined in subclause 9.2 of ISO/IEC 9995-9:2026 titled “The special mode "IPA"”.
Several variants are presented in 4.5, which only differ in the extent of function keys and the presence of a
graphic key at position C12, D13, or E13.
4.2 Layout table
Table 1 lists the characters in the primary and secondary group of the Latin International keyboard together
with their hexadecimal values assigned by ISO/IEC 10646.

a
If a graphic key at position C12 or E13 is present instead of one at position D13, the specification in this row is valid for that key.
b
This is a diacritical mark to be implemented as a dead key. See 4.3.3 for the keytop engravings.
c
This is a special diacritical mark to be implemented as a dead key. See 4.3.3 for the keytop engravings.
d
This may be implemented as a dead key (see 4.4).
e
This is a diacritical mark to be implemented as a dead key. It is the variant of the diacritical mark at the same position on Level 3,
going below the base character instead of going above it (or otherwise being a variant for positions E00 and C07). It should not be shown on the
keytop separately (in accordance with the list item “Allocating obscure or rarely used characters” in subclause 4.2.3 “Usage of Level 4” of ISO/
IEC 9995-1:2026).
f
This is a diacritical mark to be implemented as a dead key only if the “Recommended handling of dead keys in environments using
ISO/IEC 10646” is implemented according to ISO/IEC 9995-11:2026, 4.2. Otherwise, this mark shall be associated directly of Level 4 of the list-
ed key position. Then, in Unicode environments, this diacritical mark is to be input after the input of the base character. It should not be shown
on the keytop separately (in accordance with the list item “Allocating obscure or rarely used characters” in subclause 4.2.3 “Usage of Level 4” of
ISO/IEC 9995-1:2026).
g
This is a “spacing modifier letter”. See 4.3.3 for the keytop engravings.
h
This is a diacritical mark spanning over two base characters. Such marks are entered after the first base character, followed by the
second base character. See 4.3.3 for the keytop engravings.
i
This is a special or an invisible character. See 4.3.3 for the keytop engravings.
j
Invisible characters enterable by the space bar in any group or level do not need to be shown on the keytop. See 4.3.3 for the keytop
engravings.
