Working with Chinese text is the hard part of my solution (described in full
in freebsd-current at freebsd.org). In brief it's about moving FreeBSD to UTF-8
completely and making syscons map UTF-8 to selected 8-bit charset for
displaying (a failsafe solution). It seems that this makes syscons somewhat
more usable for some people, but not for from East Asia, am I right?
I was thinking of how to make working with Chinese filenames possible under
syscons, but the help of a native speaker/writer would help much, because I
know only basic facts about that matter.
I see two alternatives of displaying unicode code points that do not fit
into selected 8-bit display charset:
1) Substituting with some character, like '?'. This is very affordable
solutiuon, but makes inconvenient working with files having names that do
not fit into selected charset.
2) Substituting with encoded code point value like "#1234;". This is more
complex solutuon, if correct baskspacing and things like that are required.
I am not ready to implement it.
In any case, it would be nice to have some "magic" implemented: if copying
a text with substitued code points and then pasting it would case the
original UTF-8 sequence to be inserted.
For all folks I'd like to explain again that I'm not discussing correct
rendering of non-latin scripts. It's not possible to render Devanagari in
character mode. And approach that Linux console takes is partial. The cost
of full solution is like X, freetype, freebidi and so on.
Tz-Huan, could you comment on the proposed solution? From your point of
view, are proposed changes in syscons useful?
Again, this does not affect X, Firefox, etc, but would make possible to have
the whole system using UTF-8 out of box.
