TypeConditionally Required (1C)
KeywordSpecificCharacterSet

Character Set that expands or replaces the Basic Graphic Set.

See Section C.12.1.1.2 for Defined Terms.

Section C.12.1.1.2

C.12.1.1.2 Specific Character Set

Specific Character Set (0008,0005) identifies the Character Set that expands or replaces the Basic Graphic Set (ISO 646) for values of Data Elements that have Value Representation of SH, LO, ST, PN, LT, UC or UT. See PS3.5.

If the Attribute Specific Character Set (0008,0005) is not present or has only a single value, Code Extension techniques are not used. Defined Terms for the Attribute Specific Character Set (0008,0005), when single valued, are derived from the International Registration Number as per ISO 2375 (e.g., ISO_IR 100 for Latin alphabet No. 1). See Table C.12-2.

Note

To use the single-byte code table of JIS X0201, the value of Attribute Specific Character Set (0008,0005), value 1 should be ISO_IR 13. This means that ISO-IR 13 is designated as the G1 code element, which is invoked in the GR area. It should be understood that, in addition, ISO-IR 14 is designated as the G0 code element and this is invoked in the GL area.

If the Attribute Specific Character Set (0008,0005) has more than one value, Code Extension techniques are used and Escape Sequences may be encountered in all character sets. Requirements for the use of Code Extension techniques are specified in PS3.5. In order to indicate the presence of Code Extension, the Defined Terms for the repertoires have the prefix "ISO 2022", e.g., ISO 2022 IR 100 for the Latin Alphabet No. 1. See Table C.12-3 and Table C.12-4. Table C.12-3 describes single-byte character sets for value 1 to value n of the Attribute Specific Character Set (0008,0005), and Table C.12-4 describes multi-byte character sets for value 2 to value n of the Attribute Specific Character Set (0008,0005).

Note

A prefix other than "ISO 2022" may be needed in the future if other Code Extension techniques are adopted.

The same character set shall not be used more than once in Specific Character Set (0008,0005).

Note

For example, the values "ISO 2022 IR 100\ISO 2022 IR 100" or "ISO_IR 100\ISO 2022 IR 100" are redundant and not permitted.

There are multi-byte character sets that prohibit the use of Code Extension Techniques. The following multi-byte character sets prohibit the use of Code Extension Techniques:

These character sets may only be specified as value 1 in the Specific Character Set (0008,0005) Attribute and there shall only be one value. The minimal length UTF-8 encoding shall always be used for [ISO/IEC 10646].

Note

  1. [ISO/IEC 10646] now prohibits the use of anything but the minimum length encoding for UTF-8. UTF-8 permits multiple different encodings, but when used to encode Unicode characters in accordance with ISO 10646-1 and 10646-2 (with extensions) only the minimal encodings are legal.

  2. The representation for the characters in the DICOM Default Character Repertoire is the same single byte value for the Default Character Repertoire, [ISO/IEC 10646] in UTF-8, [GB 18030] and [GBK]. It is also the 7-bit US-ASCII encoding.

  3. The [GBK] character set is a subset of the [GB 18030] character set, which is restricted in its one- and two-byte code points. In this subset, the [GBK] character set follows the exactly same encoding rules of [GB 18030].
