Subject: Shift-JIS/Unicode mapping in JAVA

I guess that you used the charset name "Shift_JIS". Would you try to
Two Shift-JIS variations are registed in the IANA registry:
"Shift_JIS" and "Windows-31J". The former is for JIS X 0208 and the
latter is for Microsoft's CP932. "Windows-31J" was proposed by one of
Microsoft's Japanese engeneers.
"Shift_JIS" is aliased to JIS X 0208 in JDK 1.1-1.1.7. But it is
re-aliased to CP932 in JDK 1.1.8-J2SE 1.4 ("Windows-31J" is also
aliased to CP932) and we found problems that we can't select the right
character encoding in J2EE platforms or there is a mapping
mis-matching between JDK and Xerces (Xerces has an original alias
table to alias "Shift_JIS" to JIS X 0208).
So we requested the following alias change and it was accepted in J2SE
Shift_JIS -> JIS X 0208's shift-jis encoding.
Windows-31J -> Microsoft's CP932
See changes of J2SE 1.4.1.
