Hi,

This is about the DBCS character sets cp950, cp949, etc. that might get
registered with IANA by Microsoft.

Isn't it great to have standards?

That seems rather unfortunate :-(  Many people get confused about what is 
codepage 950.  There is more than one Big5 implementation.

Sun's Java uses cp950 to mean ibm-950, and Sun's Java has another mapping 
table called Big5, which is different from cp950.  Since Microsoft wants 
this alias I presume that Microsoft wants cp950 to map to something like 
windows-950, which is closer to ibm-1373.  From the point of view of IANA, 
this may be the Big5 alias.  In order to add confusion to this problem, 
Microsoft overloads the meaning of windows-950.  You can download a patch 
to add HKSCS support to windows-950 on your Windows machine.  So on some 
machines, windows-950 means Big5, while on others it means Big5-HKSCS, 
which contains incompatible Unicode mappings with each other.

Sun's Java also uses cp949 to mean ibm-949, which is different from 
windows-949.  Oh, and there is more than one flavor of ibm-949, and Sun's 
Java uses cp949c to denote the alternate ibm table.

What a mess :-(
