UTF-8 on 8.0-CURRENT: Yes We Can!

[Alexander Churanov]

Vladimir,

I have been working on this for some time in February.

All changes are checked into Perforce branch named "syscons-utf8". See
http://p4db.freebsd.org/branchView.cgi?BRANCH=syscons%2dutf8 for
details. Basically, mapping unicode to selected 8-bit charset is
implemented, as well as changes for vidcontrol(1) to manipulate it.

What's left:

1) New ioctls should be reviewed.
2) Documentation is not written.

So then I need to negotiate implementation plan with Ed and may start
with finishing that work right on the next week.

I guess this code will not go into 8.0. In this case I may start with
full unicode rendering with no mapping upon finishing code based on
mapping approach. We have discussed it with Ed and come to conclusion
that it is not hard to implement.

Sincerely,
Alexander Churanov
