Code page 950 is the code page used on Microsoft Windows for Traditional Chinese. It is Microsoft's implementation of the de facto standard Big5 character encoding. The code page is not registered with IANA,[1] and hence, it is not a standard to communicate information over the internet, although it is usually labelled simply as big5, including by Microsoft library functions.[2]
Code page 950
Code page 950 layout as implemented by Microsoft (top, MS-950 or IBM-1373) and IBM (bottom, IBM-950).
IBM's CCSID 950 comprises single bytecode page 1114 (CCSID 1114) and double bytecode page 947 (CCSID 947),[4][5][6] and, while also a Big5 variant, is somewhat different from Microsoft's code page 950, incorporating some of the ETEN extensions for lead bytes 0xA3,[7] 0xC6,[3][8] 0xC7[9] and 0xC8,[3][10] while omitting those with lead byte 0xF9 (which Microsoft includes), mapping them instead to the Private Use Area as user-defined characters.[3][11] It also includes two non-ETEN extension regions with trail bytes 0x81–A0, i.e. outside the usual Big5 trail byte range but similar to the Big5+ trail byte range: area 5 has lead bytes 0xF2–F9 and contains IBM-selected characters, while area 9 has lead bytes 0x81–8C and is a user-defined region.[12]
Microsoft updated their version of code page 950 in 2000, adding the euro sign (€) at the double-byte code 0xA3E1. IBM refers to the euro sign update of their Big-5 variant as CCSID 1370 (which includes both single-byte (0x80) and double-byte euro signs).[13] It comprises single byte code page 1114 (CCSID 5210) and double byte code page 947 (CCSID 21427).[13][14][15]
For better compatibility with Microsoft's variant in IBM Db2, IBM also define the pure double-byte Code page 1372[16] and associated variable-width CCSID 1373, which includes only the double-byte euro sign[17] and matches Microsoft behaviour in which extension regions are included.[18][19][20][21][22]
Single byte codesedit
The following are the single-byte graphical characters included by IBM. The codes 0x00 though 0x1F and 0x7F may be used for C0 control codes instead, depending on context (compare code page 437, code page 897). As noted above, the single-byte euro sign at 0x80 is not included in IBM CCSIDs 950 or 1373, nor by Microsoft.
