7 Identification of the character set

7.1 Identification according to ISO/IEC 2022

and ISO/IEC 4873

When the identification methods of ISO/IEC 8824-1

are used this part of ISO/IEC 8859 shall be

identified by the following object identifiers:

The graphic characters of this part of ISO/IEC 8859

constitute a single coded character set. However in

– character set

{ iso standard 8859 4 abstract-syntax (1) }

accordance with ISO/IEC 2022 and ISO/IEC 4873

the code table of this part of ISO/IEC 8859 may be

considered to consist of the following components:

– coded representations

{ iso standard 8859 4 transfer-syntax (0) }

– The character SPACE represented by bit

combination 02/00;

– a 94-character G0 graphic character set

represented by bit combinations 02/01 to 07/14;

– a 96-character G1 graphic character set

represented by bit combinations 10/00 to 15/15.

When the identification methods of ISO/IEC 2022 or

ISO/IEC 4873 are used this part of ISO/IEC 8859

shall be identified by the following pair of

designation functions:

GZD4 04/02 (ESC 02/08 04/02)

G1D6 04/04 (ESC 02/13 04/04)

NOTE – The corresponding escape sequences are

shown in parentheses.

The corresponding object descriptors shall be:

– character set "ISO 8859 part 4 repertoire"

– coded representations "ISO 8859 part 4 code"

7.3 Identification using the ISO International

T register of coded character sets to be used

with escape sequences

According to 7.1 above the character set of this part

of ISO/IEC 8859 may be considered to consist of

X the character SPACE, a 94-character G0 graphic

character set, and a 96-character G1 graphic

character set. The G0 and G1 graphic character

sets may be identified by the use of the Registration

E Numbers from the ISO International register of

coded character sets to be used with escape

sequences.

TWhen these registration numbers are used this part

7.2 Identification according to ISO/IEC 8824-1

(ASN.1)

In the terminology of ISO/IEC 8824-1 the character

set of this part of ISO/IEC 8859 and the

corresponding coded representations are distinct,

L and are known as the "character abstract syntax"

and the "character transfer syntax" respectively.

of ISO/IEC 8859 shall be identified by the following

pair of registration numbers:

– G0 graphic character set ISO-IR 6

– G1 graphic character set ISO-IR 110
