I've just subscribed to this list to ask you for an opinion about my
feature request:!msg/gnu.emacs.bug/SK-RO_OG_GQ/BmUzA-23AgAJ

Unfortunately at these addresses you can find only old posts, without the
recent live exchange of mails with Eli Zaretskii. I quote below the most
important fragments of them.

Actually Eli Zaretskii made also some interesting comments about how Unicode
support is implemented, I can forward them too if you are interested.

If you think this is outside you scope of interest, just let me know.
