I.3 Example of Long Text Value Representation in the Korean Language Without Explicit Escape Sequences Between Character Sets

Example I.3-1. Example of Long Text Value Representation in the Korean Language Without Explicit Escape Sequences Between Character Sets

Hangul (ISO IR 149) and ASCII (ISO 646) character sets can be used intermingled without explicit escape sequences between them. The Hangul character set ISO IR 149 is invoked to the G1 area, so this invocation doesn't affect the G0 area to which the ASCII character set has been invoked. The following is an example of a Long Text value representation that includes ASCII and Hangul character set.

Specific Character Set:

  • (0008,0005) \ISO 2022 IR 149

Character String:

  • The first line includes 한글 .

    The second line includes 한글 , too.

    The third line

Encoded String:

  • ESC 02/04 02/09 04/03 The first line includes 한글 .

    ESC 02/04 02/09 04/03 The second line includes 한글 , too.

    The third line

Once having invoked the ISO IR 149 character set to G1 area by the escape sequence in the head of line, one can use Hangul and ASCII intermixed in that line.
