[9fans] latin1() and unicode()?

[9fans] latin1() and unicode()?

[Dan Cross]

/sys/src/9/port/latin1.c contains these two useful routines for
converting character strings into unicode runes.  this is what the
keyboard driver uses to translate, eg, Latin, ':', ')' into the Unicode
smiley face character, for instance.

It seems as though this code could have utility outside of the kernel;
is there any reason not to move it into libc?

no, the latin1 code is broken.  sure i could type 'em all,
but when i wanna do it the normal way by typing the character
directly i lose.

getting this stuff right is hard and a us-centric world view
won't help you one iota.

yep, i see that.

i see that too.

that's not the fault of that code.
we've done French and German keyboard drivers for Inferno
(non-PC keyboards) without having to change the latin1 stuff.
kbd.c is another matter.

(Actually, it's pretty easy, but it was throwing me off for a
while.)

Hmm...  Fair enough.

It'd be very useful for writing user-level software to
drive serial keyboards.  :-)  But including it out of
the kernel shouldn't be so hard.

Turning off the serial console on the bitsy; now that's
hard (or at least tedious).

I'd tend toward including it manually where
you want it until you're sure it's useful
enough to be in the library.  Personally
I don't see it as too applicable elsewhere.
