Module text

This module contains reusable components for encoding and decoding text in DICOM data structures, including support for character repertoires.

At the moment the following character sets are supported:

Character Set	decoding support	encoding support
ISO-IR 6 (default)	✓	✓
ISO-IR 100 (ISO-8859-1): Right-hand part of the Latin alphabet no. 1, the Western Europe character set	✓	✓
ISO-IR 101 (ISO-8859-2): Right-hand part of the Latin alphabet no. 2, the Central/Eastern Europe character set	✓	✓
ISO-IR 109 (ISO-8859-3): Right-hand part of the Latin alphabet no. 3, the South Europe character set	✓	✓
ISO-IR 110 (ISO-8859-4): Right-hand part of the Latin alphabet no. 4, the North Europe character set	✓	✓
ISO-IR 144 (ISO-8859-5): The Latin/Cyrillic character set	✓	✓
ISO-IR 192: The Unicode character set based on the UTF-8 encoding	✓	✓
GB18030: The Simplified Chinese character set	✓	✓
JIS X 0201-1976: Code for Information Interchange	x	x
JIS X 0208-1990: Code for the Japanese Graphic Character set for information interchange	x	x
JIS X 0212-1990: Code of the supplementary Japanese Graphic Character set for information interchange	x	x
KS X 1001 (registered as ISO-IR 149) for Korean Language	x	x
TIS 620-2533 (1990) Thai Characters Code for Information Interchange	x	x
GB2312: Simplified Chinese character set	x	x

These capabilities are available through SpecificCharacterSet.
