Code page 950
Code page 950 is Microsoft's implementation of the de facto standard Big5. The code page is not registered with IANA, and hence, is not a standard to communicate information over the internet. The major difference between code page 950 and Big5 is the incorporation of some ETEN characters at F9D6-F9FE (碁, 銹, 裏, 墻, 恒, 粧, and 嫺) and 34 box drawing characters and block elements. It was updated in 2000 with the addition of the euro sign (€), at 0xA3E1. This update is called Code page 1370 by IBM (as IBM did not change Code page 950), but Microsoft Windows refers to it as a Code page 950 update.
Code page 951
Code page 951 is a misnomer for a hack used in HKSCS-2001 support in Windows XP, derived from the file name. The "new" code page is a replacement for CP950 with Unicode mappings for some Extended User-defined Characters (EUDC) found in HKSCS. HKSCS characters without a Unicode mapping are assigned a Unicode Private Use Area (PUA) code point following previous practises.
Private Use Area usage
This mapping is also used in HKSCS where a given glyph is not yet found in the Unicode revision specified.
