Thanks.

I could predict your answers in advance.  I need to hear a second
opinion, from someone who does read these languages, because the issue
at hand is how the charset information affects the font(s) selected
for displaying the text, and how important are the differences in
those fonts to CJK users.

??? It's a UTF-8 file with markup.  Do you have the same problems with
HTML and XML files?

(I'm not saying that we should use the same technique for Lisp files,
of course.)
