ISO/IEC 10646:2020/Amd.1:2023(E) Amendment1
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 interna-
tional 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).

7.4 Naming of characters
In the paragraph after list item g), replace the sentence as follows:
Some characters may have one or more alternate names, called character name aliases. See 7.5.
Introduce a new sub-clause 7.5 with a new Table 2, renumbering the following tables and sub-clauses as
appropriate.
7.5 Character name aliases
This document has a mechanism for the publication of additional, normative formal aliases for char-
acters. These formal aliases are known as character name aliases. They function essentially as auxilia-
ry names for a character. Their main usage is to provide correction for known mistakes in character
names, but they have other usages such as providing string identifiers for control functions.
Character name aliases are listed in the file NameAliases.txt (see Clause 2). That file also documents
the ‘type’ field which distinguishes among different kinds of character name aliases, as shown in Ta-
ble 2.

ISO/IEC 10646:2020/Amd.1:2023 (E) Amendment 1
Table 2: Types of character name aliases
Type Description
Corrections for mistakes in the character names which
correction
cannot be fixed after publication of the standard
ISO/IEC 6429 names for C0 and C1 control functions,
control and other commonly occurring names for these control
functions
alternate Widely used alternate names for format characters
Several documented labels for C1 control code points
figment
which were never actually approved in any standard
Commonly occurring abbreviations or acronyms for
abbreviation control functions, format characters, spaces and varia-
tion selectors

Character name aliases follow the same rules as character names. See Clause 27.
8 Revision and updating of the UCS
Remove the NOTE which is superseded by sub-clause 7.5.
11 UCS Encoding schemes
11.5 UTF-16
Replace the third paragraph as follows:
In the absence of signature or a higher-level protocol, the octet order of the UTF-16 encoding scheme
is that the more significant octet precedes the less significant octet.
12 Use of control functions with the UCS
Replace NOTE 3 with the following text and note:
Control functions have associated string identifiers specified by the ‘control’ type in the file Name-
sAliases.txt (see Clause 2). Many of these control functions have multiple identifiers based on various
environments.

NOTE 3: For example, the control characters 000E and 000F are named SHIFT-OUT and SHIFT-IN respectively in a 7-
bit environment and LOCKING-SHIFT ONE and LOCKING-SHIFT ZERO respectively in an 8-bit environment.
17.6 Variation selector and variation sequences
17.6.1 General
In the second paragraph, replace ‘three Mongolian Free Variation Selectors (FVS1 to FVS3)’ by ‘four Mongolian
Free Variation Selectors (FVS1 to FVS4)’.
17.6.2 Standardized variations sequences
In the list item describing Mathematical symbols, remove the note and add the following sentence after ‘Mathemati-
cal symbol’:
Some variation sequences are used to describe a graphic variant while others are used to describe style
variant such as Chancery style versus roundhand style.

order when present in a first row. That row is not shown if none of these sources are specified for that
code point. An optional second row may be displayed to show the Hanzi M source, the Unicode U
sources, the UK UK source, and the SAT S source. Because at least one of these ten sources (G, H, T, J, K,
V, M, U, UK, and S) exists for any code point in that block, there is always one row visible for each code
point in that block. The KP source glyphs are not show for that block for lack of suitable font.

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 interna-
tional 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).
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. ISO and IEC 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

7.4 Naming of characters
In the paragraph after list item g), replace the sentence as follows:
Some characters may have one or more alternate names, called character name aliases. See 7.5.
Introduce a new sub-clause 7.5 with a new Table 2, renumbering the following tables and sub-clauses as
appropriate.
7.5 Character name aliases
This document has a mechanism for the publication of additional, normative formal aliases for char-
acters. These formal aliases are known as character name aliases. They function essentially as auxilia-
ry names for a character. Their main usage is to provide correction for known mistakes in character
names, but they have other usages such as providing string identifiers for control functions.
Character name aliases are listed in the file NameAliases.txt (see Clause 2). That file also documents
the ‘type’ field which distinguishes among different kinds of character name aliases, as shown in Ta-
ble 2.

12 Use of control functions with the UCS
Replace NOTE 3 with the following text and note:
Control functions have associated string identifiers specified by the ‘control’ type in the file Name-
sAliases.txt (see Clause 2). Many of these control functions have multiple identifiers based on various
environments.

NOTE 3: For example, the control characters 000E and 000F are named SHIFT-OUT and SHIFT-IN respectively in a 7-
bit environment and LOCKING-SHIFT ONE and LOCKING-SHIFT ZERO respectively in an 8-bit environment.
17.6 Variation selector and variation sequences
17.6.1 General
In the second paragraph, replace ‘three Mongolian Free Variation Selectors (FVS1 to FVS3)’ by ‘four Mongolian
Free Variation Selectors (FVS1 to FVS4)’.
17.6.2 Standardized variations sequences
In the list item describing Mathematical symbols, remove the note and add the following sentence after ‘Mathemati-
cal symbol’:
Some variation sequences are used to describe a graphic variant while others are used to describe style
variant such as Chancery style versus roundhand style.

code point. An optional second row may be displayed to show the Hanzi M source, the Unicode U
sources, the UK UK source, and the SAT S source. Because at least one of these ten sources (G, H, T, J, K,
V, M, U, UK, and S) exists for any code point in that block, there is always one row visible for each code
point in that block. The KP source glyphs are not show for that block for lack of suitable font.
