We have to differentiate between input and output.
For output, most XML parser support Unicode only.
For input, Expat supports UTF-8, UTF-16, ISO-8859-1 and ASCII.
If you implement the unknownEmcodingHandler() then Expat can
support more encodings.
If you check out patch # 888879, you will find that someone
supplied such an implementation for the gb3212 encoding.
However, the standard encoding is Unicode, which supports basically
all characters of all languages, including Asian languages.
If you have a choice, I recommend to abandon the older
multi-byte encodings for Asian characters and switch to unicode.
