Hello,
The 8x16 and Sun 12x22 kernel fonts I tried seem to lack some standard
glyphs necessary to represent the entire ISO-8859-1 charmap; I am talking
about all accented capital vowels except for '?'.
This seems to happen in both 2.2.16 as well as in 2.2.18.
Is this intentional? If so, why?
How can I override this behaviour?
Thank you.
Cheers,
Mack Stevenson

They're probably CP 437 fonts. Just load your own; e.g. "setfont lat1u-16".

I know that, but unfortunately all the fonts I found for use with the kbd
and console-tools packages are much smaller than 12x22, making them hardly
legible (to me) on high dpi screens: that's why I even tried the ones in the
kernel. :-)
[Is there any easy way for you to create larger console fonts out of the
8x16 Latin* ones you already wrote?]
"setfont -h22 [font]" doesn't work, too.
Anyway, I have already pinned down the source file (in 2.2.18) -
drivers/video/font_sun12x22.c - and would like to try to change this. Yet it
seems like the kernel boots using the CP437 charmap, so this would need to
be modified, too - I suppose that the relevant file is
drivers/char/consolemap.c.
- How can I instruct the kernel to use the ISO-8859-1 character map?
drivers/char/consolemap.c contains three different translation tables -
CP437, ISO-8859-1 and VT100 mapped to Unicode -; how can I choose one of
them?
- Or shouldn't I even bother about this since in the ASCII range CP437 and
ISO-8859-1 map to the same characters? May I just boot the kernel using an
unmatched pair of (CP437) charmap and (ISO-8859-1) font, feeling at ease
because the kernel won't try to print any non-ASCII characters, and only
later, in userspace, call loadunimap?
Am I understanding this correctly?
Thank you,
Mack

Not really.
You're much better off designing a larger ISO-8859-1 font and load in in
user space. You can use the 12x22 font in the kernel as a base.

I have converted my fonts by hand (with a GW-BASIC proggy) from bitmap
to .c, though not the SUN fonts for ISO but the PC fonts for cp437.
I did this because I do not like e.g. the glyph "0" in standard font
and included the "Euro" sign. (I use the same for DOS and Linux now,
and even Windoze recently got it as Terminal font!)
My second suggestion: code it as .psfu and load it by setfont, including
the appropiate console-map. AFAIK all the kernel default fonts are cp437
(linux/drivers/char/cp437.uni; consolemap.*)

Something that would be really good is if someone could contribute PSF
(v1 and v2) support for gfe <http://www.gnu.org/software/gfe/gfe.html>
or some other free font editor.

kbd-1.05 comes with sun12x22.psfu, which essentially is the kernel font
together with a unimap.

I always do it by a BASIC programme under DOS (yep I know
this isn't pure but I have a font editor from S-DOS aka
PTS-DOS (the free version)). The SFE.COM allows me to design
8x8 8x12 8x14 8x16 fonts; the unicode table I write in the
MC or VC (NC clone for DOS) editor; my BASIC pgm converts
them together to PSFU. It's very easy once you read the psf
docs.
It's a pity that I've to mkfs the DOS partitions of my HDDs
every handfull of weeks, otherwise I'd put them onto a ftp
server somewhere. But I call you to try it by yourself.
(perl prolly isn't that easy coz it goes to binary values,
but GW-BASIC is fine)

I published a DOS-based PSF editor a long, long time ago (look for
fontedit.exe; if it isn't on the net anywhere remind me and I'll put it
back up.) Use psfaddtable then to combine it into PSFU.
However, having something running under Linux would make more sense.

Thank you for your help; I'll try to use a psf editor on the Sun 12x22 font
in the new kbd package.
Cheers,
Mack

Note, that I also have a SuSE12x22 font, which is based on the Sun font,
some charcaters slightly changed and added lots of 8859-1 symbols.
Isn't it included in kbd-1.04 and later, Andries?
I also have a patch to make it available for the kernel ...

It may be that that is the one called sun12x22.psfu in kbd-1.05.
I think I first took your first version and later replaced it
with your latest version. Perhaps I did some work on it myself
as well, but maybe that was first for kbd-1.06. There was also
a Polish contribution for kbd-1.06, so the 1.06 version will have
a few more symbols, I think.

Hello all..
I'm interested in making a 16x32 console font, so I can run my 21"
display at 100x37 text. I've asked on the framebuffer list already, but
have heard no reply, and the list seems to be defunct.
Since it's a fixed-frequency display, I want to have the framebuffer and
basic font in-kernel and loaded at boot time. I'm not sure where to find
the necessary tools/documentation to do all the steps, though. Could
someone point me in the right direction?
