Hm, there's MULE<=>BIG5 converters but I don't see any for GBK or
GB18030. Also, it looks like the MULE<=>BIG5 converters do some
re-encoding, so it's not clear to me whether they're lossless,
which I assume is the concern driving this request.
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.
