# I Character Sets and Person Name Value Representation in the Korean Language (Informative)

## I.1 Character Sets For The Korean Language in DICOM

KS X 1001 (registered as ISO-IR 149) is used as a Korean character set in DICOM. This character set is the one most broadly used for the representation of Korean characters. It can be encoded by ISO 2022 code extension techniques, and is registered in ISO 2375.

The Escape Sequence is shown for reference in Table I.1-1 (see PS3.3)

Table I.1-1. ISO/IEC 2022 Escape Sequence for ISO-IR 149

| ISO-IR 149
--- | ---
G0 set | ESC 02/04 02/08 04/03
G1 set | ESC 02/04 02/09 04/03

### Note

1. ISO-IR 149 is only used as a G1 set in DICOM.

2. The Korean character set (ISO IR 149) is invoked to the G1 area. This is different from the Japanese multi-byte character sets (ISO 2022 IR 87 and ISO 2022 IR 159), which use the G0 code area. Japan's choice of G0 is due to the adoption of an encoding method based on "ISO-2022-JP". ISO-2022-JP, the most familiar encoding method in Japan, and uses only the G0 code area. In Korea, most operating systems adopt an encoding method that invokes the Hangul character set (KS X 1001) in the G1 code area. So, the difference between code areas of Korean and Japanese character originates in convention, not a technical problem. Invocation of multi-byte character sets to the G1 area does not change the current DICOM normative requirements.
