I may be wrong but that seems a give-away that the PDF is
made comprehensively wrongly.  You should never see that if
you are working with single byte fonts.

I assume you are working with single byte fonts because of
your reference to BaseFont and Encoding. Type1 and TrueType
font types are always single byte fonts; it is impossible
for them to be anything else if you look at the spec. The
Encoding mechanism is clearly a 256 slot entry.

I suspect Acrobat 3 would see an operating system font by that
name and pass your glyph data directly to it without checking
the Encoding. This is defnitely wrong of it.

To work with Chinese fonts you will have to understand about
CID fonts and CMaps, as Mark noted. You will need to know exactly
what encoding your fonts use.  If you haven't read "CJKV
Information Processing", now is the time to stop using it as
a paperweight (though at 1100 pages it is a very good one).

You will also need to target Acrobat 4.0 and above; you will
need the appropriate language support installed in Acrobat or
Reader. That is, the Chinese (Traditional) or Chinese (Simplified)
language pack, depending on which you are targeting.

I suspect this may increase the complexity of your project by
an order of magitude or two, but that's CJK fonts for you...
