Yes, it's an old and outdated text (Emacs is around since 1985, and
supports multilingual text editing since 1997).  Easy to fix, and I
will fix it, but my main difficulty is with the text that uses the
script itself, which is why I asked here.  I couldn't find
copy/paste-able text for that anywhere on the Internet.

Thanks.
