Hi all :)
I have a do-it-yourself Linux box, and I'm planning to move to UTF8
(currently I'm using es_ES locale, with latin1 encoding). One of my main
concerns (apart from programs with little or no utf8 support, which I
will have to suffer) is kernel handling, because I only use the console;
I only use X and a terminal emulator if I can't avoid it.
This said, I know that the console will give me no problems
regarding character representantion (heck, I'm pretty sure that I will
be able to use even the same font I'm using right now in the console if
I get the proper unicode map), but probably will give me problems when
*entering* characters. I've read that the kernel handles accented chars,
and things like '?' (ntilde) because it assumes that any composed
character (composed using dead keys, for example) is in the latin1
range. While this is not a perfect behaviour, it will work for me.
Will the console work as it works now if I can live with latin1
accented characters only? Is there any terminal emulator *for the
console*, not for X, that handles utf8? Will I be sentenced to X to be
able to use my computer with utf8?
Don't take me bad, I really would love to spend 100MiB of RAM just
to run mutt under xterm, but for the time being I prefer the console to
work even if I must run X...
Thanks a lot! :))

Hmmm. I've not yet played with moving to utf-8 but would
man console_codes
be of help to you?

Not, because I already know the escape sequence to go back and forth
to utf-8 mode O:)) I'm going to carry some tests using Ubuntu, but since
that is a distro I'm not sure if I will be able to apply the same
solutions and mechanisms to my do-it-yourself box.
Thanks anyway for answering :)

Just tested here, it _seems_ to work right on the console with Spanish
and French accentuated characters.

fbiterm, I never dared to try though...
See you,

The switch is possible. You could try the latest development LFS LiveCD
(http://ums.usu.ru/~patrakov/test/lfslivecd-x86-6.3-pre2-r1897.iso) and see
if it works for you (be sure to CC: me if you post any feedback). It will
automatically configure the console using a simple menu-driven interface.
Some interesting programs to try there: mutt, tin, lynx, finch.

Yes.

screen, jfbterm, iterm (jfbterm and iterm are not on my CD, but you can
build them from source there - the filesystem on the CD can be written to).
Note that jfbterm and iterm expect X fonts (or unifont) to be available, and
the CD doesn't have these fonts (fully switched to Xft).

I was wrong. The problem is that input works, output works, but
copying-and-pasting with gpm doesn't work (the stable version of the CD,
http://ums.usu.ru/~patrakov/x86/lfslivecd-x86-6.2-5.iso, contains a
rejected-upstream kernel patch that hides the issue). This means that for
all serious Unicode work, you must use X.

(1) I can do <Compose><~><n> just fine on vt
(2) I can do <ö> just fine on vt too
(3) And copy+paste them both using GPM too, again w/o probs
so not sure where your problem is. I do however have a patch that
you could try should a problem arise. I should repost and ask
around again and beat until it's in :)

Hello to all,
the following patch still lingers in my tree, can we have it merged?
This patch fixes dead keys and copy/paste of non-ASCII characters
in UTF-8 mode on Linux console. See more details about the
original patch at: http://chris.heathens.co.nz/linux/utf8.html

Sure, the console will work (don't know about a console terminal
emulator). I'm not very keen on compose keys - I find dead
diacriticals (like in X) are usually easier to enter, and I've got
all the dead latin1 accents working on my uk keymap. Other
diacriticals for normally-latin1 keymaps are a different matter
(e.g. caron, ogonek, dot above) - they could be mapped for a
specific letter on a specific key (e.g. AltGr z for ż ; z with dot
above) but the diacritical modifiers can't be mapped for non latin1,
at least in kbd-1.12. You can also alter the keymap to allow you do
ISO 14755 input (ctrl+shift+hex_digits) - useful for occasional
characters, if they are in your font and you can remember their
value.

Both of those are in the 0-255 range, though. I thought the issue was
with characters 256+, like č. At least on my FC6 system that doesn't
work with gpm.

The switch to utf-8 is possible, I know, but I wasn't so sure about

I was going to take a look at Linux From Scratch (and BLFS, too) for
help, but before trying anything there I wanted to be sure that the
kernel will work. Otherwise I will put my effort in building a minimal X
setup with a suitable terminal emulator.
Anyway, if everything works in the console in the LFS LiveCD, I will
be sure that I can make the change and then I'll look directly in the
LFS book for further instructions.
Thanks a lot! :)

GNU screen? I'll give it a try.

There are more terminal emulators for console than I supposed.

Well, I'll deal with that issue if I like them more than screen or
plain console.
Thanks again :)

Not a problem for me because I don't use GPM. I hate mice, and while
under X I'm forced (more or less) to use them, I don't use a mouse on
the console. I can blind type, so I prefer to keep my hands on the
keyboard. I work much more fast that way, and I haven't needed to copy
and paste between consoles ever.
Thanks anyway for the warning ;)

I only use compose keys for a bunch of characters like ? (copyright
mark) for example. For any other I use dead diacriticals (for example,
to write the accented chars for my mother tongue).

I have my keymap modified for that, and I use it as a last resort.
If I find myself using AltGr+hex (that's the key combo I use), I usually
put that character in a compose.
Thanks for the info, I'm very happy to hear that it works :)))

Cool! :)))

Right now my only problem was lack of reliable information, but that
has been fully solved by all people who answered, so my next step is to
upgrade kbd and start making tests :))

Any patch regarding a better support of utf-8 is very welcome, and I
can help you beat anybody if that will make the patch in XD
Thanks a lot for the patch (I'll try it if I face problems) and for
your answer.

By now, to fully switch to utf-8, I only need to have ?????? and
their uppercase counterparts (for people who cannot see the chars, they
are the acute accented vowels and the ntilde). I really hope that, in
the future, there are a way of fully use Unicode (and I mean the entire
range) using framebuffer in console (there probably is an emulator for
that job already, I have to check), but for the time being that's
enough.
I really don't mind if I have to use an userspace program to have
unicode support on the console (the kernel shouldn't mess with
encodings, or have utf-8 only; I don't know the current status, that's
why I asked), but if the kernel does directly the job in the console
driver, that's not bad either.

Use the ratpoison WM then.

I've got a cp437 "DOS" font loaded[1], and giving a glance at
/usr/share/kbd/unimaps/cp437.uni tells me right away:
0x01 U+263A
So I create U+263A in joe (ESC ' x 2 6 3 a), it displays fine (the
smiley character), and I can copy/paste it using GPM without
problems. Though, I have that patch[2] in my kernel. Can you check
if it works if you apply it?

I cannot reboot my machine right now, and I don't have GPM
installed, but if you give me a few days I think I'll be able to test.
I have to upgrade the kernel too (I'm using 2.6.19.5), so make it a week
O:)) I'll test ASAP.
And thanks for the patch :))
