Lynx and Unicode

[Mario Lang-2]

Hi.

Since I've once read (and believed) that Lynx is not fit for Unicode
consoles, I'd like to correct this false knowledge:
You can use lynx in unicode consoles with brltty from experimental
by configuring the CHARACTER_SET configuration option.  If you
put something like:

CHARACTER_SET:UNICODE (UTF-8)

in your /etc/lynx.cfg, lynx will display umlauts and thelike correctly.

If you have a braille unicode capable font loaded, it should also
be able to represent unicode braille correctly, see
http://delysid.org/music/braille.html for an example.

Samuel: Did you already submit your unicode braille tables to Debian?
It would be nice if we could select a unicode braille font in the
default system, not needing to fetch and untar a separate tarball...

They are in the console-data package, yes.

About lynx, it should select the encoding according to the current
locale's charset, see elderly bug #277200...

Nice, I see the .psf files in there.   But I could not find the
necessary unimap anywhere.  Can you please shed a little light on this?

Oops, it looks like it got forgoten in the bug report, and since I had
it already installed, I never noticed that.

Btw, I was thinking about maybe adding an option to setfont, that would
automatically extend the loaded 256-char font with braille patterns.
That would avoid having to write lat2brl, lat4brl, lat7brl, etc.

OK, I guess you will follow up on this one then?

or lat1brl, which is what I'd like to use.
This also answers my question regarding duplicity.  Yes, I think
extending setfont (or whatever is actually non-deprecated these days)
would make sense, since duplicating all the existing fonts
seems like very bad and error-prone.

Already done so, yes.

Maybe it could be made more generic by permitting to give two 256
character fonts. That may be useful for people who often use two very
different scripts.

Actually it is _already_ implemented :)

I have added brl-{08,10,12,14,16} files to the linux-brl-console, and
you can simply set

CONSOLE_FONT="lat9w-08 brl-08"

in /etc/kbd/config!  I'll submit those to console-data as well.

That sounds like something.  Pardon my ignorance, but how
does this work together with the unimap?  Will the fonts be mapped
correctly back, or are they just set for display?

I guess this supposes that the fonts have the unimap included (which is
usually the case), so that it can merge the two maps and things work
fine.

I assume you mean the tarball on brl.thefreecats.org?  I only found brl-NN.c
files in there.  Is the result of executing these binaries what is supposed
to be copied to /usr/share/consolefonts/brl-NN ?

Yes.

Yes, just run make.  I should have left the PSFs in the tgz actually.
Now I have, you can just re-download it.
