Yes you're right. My kbd-package was a little bit outdated (kbd_mode -u
was broken and resulted in raw mode).

But improvements are possible:

1. There are problems with history scrolling in bash where the text is
shifted left.

2. There are exist no keymaps for Unicode. (Or at least I didn't find
them in the kbd distribution).

3. Applications are limited to 512 characters. This means that
an application always has to ask the kernel what characters are
available, or to believe, that the user hat set up the correct
font/fontmap/keymap combination. This is ok as long as you use only
your own texts. For unknown documents you can only open and pray.
The application *could* load appropriate fonts/keymaps. But in the
way fonts/keymaps are stored today you would have to read in all
fonts/keymaps and search for the most appropriate and this doesn't
guarantee, that you find all chars if they only in different files...
There should be at last a kind of registry for these files.

4. A graphical console would make life easier, if you can download large
fonts ...

Yes I agree about GGC. But as far as I understood their docu, it's
available only after kernel bootup (but can be easily changed to
go completely into the kernel...).

Sometimes reading your replies I thought we are talking two different things.
In my opinion Unicode should solve problems not create new ones. The idea is
to have *one* "codepage" instead of hundreds. In this point the handling
Linux doesn't differ from DOS (MODE CON CODEPAGE ...). You should be able
to write in any language and even mix them if necessary. I think it's not
the idea behind Unicode that you issue 10 commands to switch between
(Don't even think of a shell script -- that's definitely not what I'm talking
about). A good Unicode implementation should work like Linux would do if all
users worldwide would need only 7bit ASCII to express everything they
want to write down. Unicode for Linux shouldn't be an emulation
(OK, it isn't but it looks like one).

Sorry if I repeating myself:
In WinNT the user has to 1 mouse click to select another keyboard and then he
simply starts typing. In WinNT a programmer has to write "#define _UNICODE"
create a Unicode-aware program. Please compare this to what has to be done
under Linux. (That's also an libc issue.)


To all who are still supporting the codepage concept: Maybe we will meet the
Borgs first. And then you will have only your Klingon codepage available.
