bug#37363: emacs and other programs do not display special characters
I'm running on guix and spanish symbols work properly, on emacs and the terminal. --- miguel@unfall ~/src/gnu/guix$ locale LANG=es_ES.utf8 LC_CTYPE="es_ES.utf8" LC_NUMERIC="es_ES.utf8" LC_TIME="es_ES.utf8" LC_COLLATE="es_ES.utf8" LC_MONETARY="es_ES.utf8" LC_MESSAGES="es_ES.utf8" LC_PAPER="es_ES.utf8" LC_NAME="es_ES.utf8" LC_ADDRESS="es_ES.utf8" LC_TELEPHONE="es_ES.utf8" LC_MEASUREMENT="es_ES.utf8" LC_IDENTIFICATION="es_ES.utf8" LC_ALL= --- I've seen some es_EC localizations instead of es_ES, could you check that's not your issue? Best regards, Miguel

Not on my user. Probably on my system. I did not know I had to add those on Guix System. Should I?

Hi,
I have been having locale-related problems too,
so maybe we can bounce enough clues around that
we can advance a little.
[ later ... I'll have to come back to locale per se,
but hope the following is useful for poking around
with fonts and unicode character and their glyphs ]
[ To the advanced, please don't be insulted by my posting
obvious stuff, as if you didn't know how to use grep and sed
and especially guix better than my examples show --
it is motivated by wanting to exchange helpful methods and info
with others also coming to guix, who might benefit from my recent
newbie experiences trying to find my way into guix city, in the
Commonwealth of FOSS :)
Hm, I wonder if we could use postgresql plus postgis to do
an openstreetmap map of guix city stores and pubs
-- and potholes and contruction blockages ;-)
]
Anyway, I have a little script which may be helpful
in generating utf8 characters for display in your
various contexts (what this (emacs) context is I'll show below):
$ uchr 229 10
å
$ which -a uchr
/home/bokr/bin/uchr
$ cat ~/bin/uchr
#!/home/bokr/.guix-profile/bin/bash
# 2019-08-19 22:25:34 ## was: #!/usr/bin/bash
# ~/bin/uchr -- print unicode characters from numeric args
# uchr 65 67 10 | od -a -t x1
# 000 A C nl
# 41 43 0a
# 003
cc="$( printf '\\u%x' "$@" )"
echo -en "$cc"
Those last two lines do all the work ;-)
(printf is a bash built-in -- type -"help printf"
at the bash command line.
(By -"foo" I mean "foo" minus the quotes :)
printf re-uses its format for each arg it encounters, so it
converts all the integers according to '\\u%x' above in uchr.
$ uchr {192..255} 10
ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖ×ØÙÚÛÜÝÞßàáâãäåæçèéêëìíîïðñòóôõö÷øùúûüýþÿ

What do you get if you try that from your login console, not gnome?
To make various fonts available to the console, you should be
able to use setfont from console bash -- see -"man setfont"
(remembering my minus-the-quotes notation :)
The {FIRST_INTEGER..LAST_INTEGER} of course generates individual
integer arguments including first and last. The 10 is a newline.
I'm pretty sure I did -"setfont sun12x22" from the console bash,
which gives you most of the 12x22 font built into the kernel.
It's got 256 character cells for its 12x22 pixel glyphs, each
represented by 22 16-bit integers using the ms12 bits with 1
as foreground, IIRC.
The sun12x22 font is pretty good, with box-drawing characters
as well most things you need in European languages (I'm familiar
with it because I wrote a little script to display the glyphs
on the frame buffer, in the pursuit of independence from huge
blobs of gooey GUI software :)
After having done -"setfont sun12x22" you can do
-"setfont -ou glyph-code-to-unicodepoint.txt" which will
give you a tab-delimited table starting ... ending like:
0x00U+
0x20U+0020
0x21U+0021
0x22U+0022
0x23U+0023
0x24U+0024
0x25U+0025
...
0xdfU+2580
0xdcU+2584
0xdbU+2588
0xddU+258c
0xdeU+2590
0xb0U+2591
0xb1U+2592
0xb2U+2593
0x01U+263a
0x5fU+f804
(BTW, this would be really easy to snarf and convert to
an assoc list mapping unicode code points to glyph indices)
That glyph 0x01 has a unicode we can discover, even though
the console font you get from -"setfont sun12x22" does not
have the glyph that is in the kernel version's glyph table:
$
$ unicode-info "$(uchr 0x263a)"
"☺":
glyph codepoint .int name...
_☺_ +U00263a 9786 WHITE SMILING FACE
$
The glyph is in the kernel's 256-glyph bit-map for
sun12x22 though, and it should be visible in a gui browser
with good unicode coverage.
You can find the kernel's bitfont defined in kernel sources
.../linux-4.14.3/lib/fonts/font_sun12x22.c (or change
the kernel version -- 4.14.3 is the last one I grop^H^Hepped around in
looking for stuff to "steal" :)
Ok, back to
$ uchr {192..255} 10

The first four A's above are really not As, as another little script
of mine that shows unicode information will show:
(you can find the source archived in a recent post of mine
https://lists.gnu.org/archive/html/guix-devel/2019-09/msg00115.html

bug#37363: emacs and other programs do not display special characters
Hello Guix: I am reporting this because there are no other similar cases on the mailing list and because I think this might be a bug and not my error. Emacs Magit and Emacs shell don't dispaly special characters (such as ñ, í, ó) on their output. It is strange because a command that includes a special character is displayed. But a special character from the output will not be displayed correcly. Those special characters are displayed correctly on afairs such as opening a file with those characters. With 'emacs -Q' I did not have that problem. When copying .emacs.d to another directory, setting that directory as HOME and running emacs with 'mkdir ~/temp', 'cp ~/.emacs.d ~/temp/' and 'HOME="~/temp" emacs', it would not use my configurations. But it would not have the problem with Emacs shell. Emacs Magit would not be available either. The same situation is with 'emacs -Q' as with 'HOME="~/temp" emacs'. Sample from BASh displaye correctly: quiliro@GSD3 ~/magit/prueba0$ git log commit 0904ec46cb737d2116d59b0b7c4f0c21a74feb70 (HEAD -> master) Author: quiliro Date: Sun Sep 8 15:43:09 2019 -0500 Modificación remota commit 5024f6d525b1b61cd269160dde07ae6f489f (origin/master) Author: ramiro.ordonez Date: Sun Sep 8 13:20:11 2019 -0500 Añadí a mi amor quiliro@GSD3 ~/magit/prueba0$ Same command sample from Emacs shell displayed incorrectly: quiliro@GSD3 ~/magit/prueba0$ git log WARNING: terminal is not fully functional - (press RETURN) commit 0904ec46cb737d2116d59b0b7c4f0c21a74feb70 (HEAD -> master) Author: quiliro Date: Sun Sep 8 15:43:09 2019 -0500 Modificación remota commit 5024f6d525b1b61cd269160dde07ae6f489f (origin/master) Author: ramiro.ordonez Date: Sun Sep 8 13:20:11 2019 -0500 Añadà a mi amor quiliro@GSD3 ~/magit/prueba0$ I am not sure if this is related that in Icecat I sometimes see square boxes with numbers inside them in place of characters. But other special characters are displayed. That is probably a missing font. It could be a separate problem. Happy hacking!
