Detailed Description

Parsed representation of a multi-valued Specific Character Set.

DICOM Specific Character Set (0008,0005) can be multi-valued with backslash separators. The first value is the default character set for G0, and subsequent values define character sets used via ISO 2022 escape sequences.

Example: "\\ISO 2022 IR 149" means:

• Component 0: empty → ASCII (ISO-IR 6) default
• Component 1: ISO 2022 IR 149 → Korean
