It does work with fonts that contain more than 255 glyphs, for
instance under utf-8; the encoding vectors that are contained in the
ttftool's encoding.h are used in the type 42 font to map characters
0-255 to a unicode value, and the PS interpreter uses this to
translate the characters that are directly present in the PS output
to the appropriate value. Since the the PS file is a single-byte file, it
makes no sense to add more values to these vectors. To support a
charset that contains more than 255 characters, you either have to
refer to the glyphs by their name (which is what we do with utf-8) or
have multiple encoding vectors and keep switching them. (It is
possible that there are other ways to handle cjk in PS, though)

You do not have to embed fonts in the PS output, there is a
checkbox in the
print dialogue that turns that off (this assumes though, that your PS interpreter
knows where to find those fonts).
I am not sure why the display/printing is not working with cjk, if I
recall, I left all the cjk font handling as it was. Unfortunately, I will
not be able to work on Abi in the next three weeks, so if someone
else could look into this, I would appreciate it.
