J Character Sets and Person Name Value​ Representation using Unicode UTF-8,​ GB18030 and GBK (Informative)​

The Unicode UTF-8 character set and the GB18030 character set may be used for multiple languages. Some of these languages​ mayalsobeencodedusingothercharactersetsthataredefinedelsewhereintheDICOMStandard.AsUnicodeUTF-8andGB18030​ encodings do not allow ISO 2022 character set replacement, these must be used for all strings in a single SOP Instance. This may​ have implications for the character set selected for the encoding of the SOP Instance.​

Since the GBK character set is fully code point compatible to the larger character set of GB 18030, and the specific examples of GB​ 18030 encoding this in Annex (J.3 and J.4) include only the Chinese characters falling in the common coding area between the two​ standards, these examples are used to demonstrate the person name and text encoding in both standards. Examples specific to GBK​ are not necessary.​

J.1 Example of Person Name Value Representation in the Chinese Language​ Using Unicode​

Example J.1-1. Example of Person Name Value Representation in the Chinese Language Using Unicode​

Person names in the Chinese language may be written in Hanzi (ideographic characters), and/or Latin (alphabetic characters). The​ Latin representation may be derived using pinyin or another Romanization method, or may be a chosen "westernized" name. The​ two component groups should be written in the order of alphabetic, then ideographic; the phonetic component group is typically not​ used (see Table 6.2-1). In this example the traditional script is used.​

Note​

1.​Somehealthcareinformationsystemsmayencodea"westernized"namewithotherpatientaliasesinaseparateattribute,​ e.g., Other Patient Names (0010,1091).​

2.​Some environments using Chinese language may use the third name component, e.g., for the Yi or Mongolian script,​ with or without the first name component. This would be similar to the Japanese and Korean name component usage.​

In the example below, the Specific Character Set attribute (0008,0005) would contain:​

J.3 Example of Person Name Value Representation in the Chinese Language​ Using GB18030​

ExampleJ.3-1.ExampleofPersonNameValueRepresentationintheChineseLanguageUsingGB18030​

Person names in the Chinese language may be written in Hanzi (ideographic characters), and/or Latin (alphabetic characters). The​ Latin representation may be derived using pinyin or another Romanization method, or may be a chosen "westernized" name. The​ two component groups should be written in the order of alphabetic, then ideographic; the phonetic component group is typically not​ used (see Table 6.2-1). In this example the simplified script is used.​
