Sun's specification only mandates the 6 charsets, but their implementation
supplies many more.
There doesn't seems to be any reason that libgcj could not supply extra
Charsets if desired. I don't think the goal should be to do the minimum
necessary to meet the spec.
The patch I posted in this message:
http://gcc.gnu.org/ml/java/2004-09/msg00174.html
might be useful. One problem I see with the current Charset implementation
is that all possible charsets are initialized when the Charset class is
initialized. It might be a good idea to only initialize them on demand.
