I based my statement on misreading the tables on here,
https://www.postgresql.org/docs/current/static/multibyte.html but, now I
see, MULE only supports big5 and EUC_CN.

My limited readings earlier about BIG5 suggested its a mess of
conflicting extensions, E-TEN and others, and the GB* stuff wasn't much
better.

Anyways, it seems to me like UTF8 is the correct server encoding for
most all uses.
