Mainly that file needs simplification: we in effect have a single
range of characters, with the possible exception of the codepoints
between 128 and 160. Also, decode-char is now a no-op when the 1st
arg is 'ucs'.
I can offer help in those parts where you don't feel you understand
the issue well enough to make the simplifications.
