UTF-8 progress bar

UTF-8 progress bar

[Julien Lepiller]

Hi Guix!

I have a patch waiting (https://issues.guix.gnu.org/59975) that will
change progress bars to use some unicode characters. I think they look
better, but I'm a bit afraid they might not look right on some config,
so I'd like to know if your terminal is able to show these characters:

"▏▎▍▌▋▊▉█▏▕"

If you are not using a unicode locale, this change will not affect you
as guix will fallback to the ascii style. If your terminal can't show
these characters and you have a UTF-8 locale (you'd run echo $LANG to
know that), please report your config (name of terminal app, locale,
fonts, …)!

It is (mate-terminal).

I can see those characters in both xfce4-terminal and kitty.

They won't work in Linux (kernel) console, despite $LANG="en_US.utf8".

Confirmed to work for me in xterm and Emacs on X11 (Guix System).

I suspect those characters could be made to work in Akib's console
if his kernel supports KMS and setfont etc ..

So I guess you, Akib, mean $LANG="en_US.utf8" in your execution
context is insufficient to make your system show the utf8 charaters
in question, not that there's no fix possible? ;)

IDK, but perhaps your app could use a wrapper that sets up a font,
along with a utf8 map that will show the necessay characters?

See:
    info setfont
and
    info showconsolefont

The characters displayed correctly in my Linux virtual console VT2
after I ran this command in Bash:

    setfont /gnu/store/iga6jf0krlh135zca7y6f1f7c4ar32z2-font-gnu-unifont-15.0.01-psf/share/consolefonts/Unifont-APL8x16.psf.gz

I was logged in as root. The variable $LC_ALL appeared to be empty. My
VT2 is managed by Greetd.

Hope that helps!

Kind regards,
Felix Lechner

Thanks, it worked!

Should we use the GNU Unifont [1][2] for virtual terminals by default?

With support for the languages below, it may be superior to whatever
we are using currently.
