As I said above, you just need to enumerate the chars individually rather
than use char-ranges in regexps.  I.e. you ned to replace things like "a-d"
with "abcd".  It may result in absurdly large regexps and it may be
a problem in itself, but in that case the only better solution would be to
restructure the code so as not to use regexps, or use category classes or
something like that.
