[solved] urxvt and aterm don't show characters correctly

Hi,

I noticed urxvt and aterm don't always show all characters correctly, here's a picture of the lines "find" outputs in:

urxvt (rxvt-unicode-patched 9.31-3; rxvt-unicode-terminfo 9.31-4)

aterm (aterm 1.0.1-7)

xterm (xterm 387-1)

$ locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

 $ cat ~/.Xressources
Xft.dpi:		96
Xft.antialias:		true

URxvt.font:		xft:Droid Sans Mono:antialias=false:size=10
! URxvt.font:		-*-droid sans mono-*-*-*-*-14-*-*-*-*-*-*-u
URxvt.boldFont:		xft:Droid Sans Mono:bold:antialias=false:size=10
URxvt.italicFont:	xft:Droid Sans Mono:italic:antialias=false:size=10
URxvt.bolditalicFont:	xft:Droid Sans Mono:bold italic:antialias=false:size=10

Since aterm is also affected, I'm not sure the urxvt.font is the culprit.

Funny thing is: if I type the ' it is displayed perfectly in urxvt, aterm and xterm.

xprop says that:
- aterm is using WM_LOCALE_NAME(STRING) = "C"
- urxvt ad xterm are using WM_LOCALE_NAME(STRING) = "en_US.UTF-8"

How do I get urxvt to display all the characters correctly all the time_

Re: [solved] urxvt and aterm don't show characters correctly

Looks more like a locale than a font issue.

localectl
locale -a
cat /proc/$PPID/cmdline 
tr '\0' '\n' < /proc/$PPID/environ | grep -E 'LC|LANG'
cat /proc/$$/cmdline 
tr '\0' '\n' < /proc/$$/environ | grep -E 'LC|LANG'

Re: [solved] urxvt and aterm don't show characters correctly

It is probably worth noting aterm is discontinued and does not support UTF-8.

True. I was surprised to find that relic on my computer still... urxvt is the terminal emulator I use.

@Seth:

 
$ localectl 
System Locale: LANG=en_US.UTF-8
    VC Keymap: (unset)         
   X11 Layout: (unset)      

$ locale -a
C
C.utf8
de_DE.utf8
en_US.utf8
POSIX

$ cat /proc/$PPID/cmdline 
urxvt-nameurxvt-ws3-left

$ tr '\0' '\n' < /proc/$PPID/environ | grep -E 'LC|LANG' 
LANG=en_US.UTF-8

$ cat /proc/$$/cmdline 
bash

$ tr '\0' '\n' < /proc/$$/environ | grep -E 'LC|LANG' 
LANG=en_US.UTF-8

Let me know if you need further info.

Re: [solved] urxvt and aterm don't show characters correctly

The locale environment looks innocent enough, still it's what I'd expect if you ran eg. "LC_ALL=C urxvt"

What happens if you run

LC_ALL=en_US.UTF-8 urxvt

?

Re: [solved] urxvt and aterm don't show characters correctly

Still the same, an â instead of a `.

Just for kicks I built rxvt-unicode-truecolor-wide-glyphs (replaced rxvt-unicode-patched as well as rxvt-unicode-terminfo) et voilà: the ` is displayed correctly.

Then I rebuilt rxvt-unicode-patched and installed rxvt-unicode-terminfo: ` is broken again.

So I think I'll switch to rxvt-unicode-truecolor-wide-glyphs.
TBH, I don't know half the stuff they patch into rxvt-packages in AUR. I believe initially (maybe 15 years ago) I chose a specific AUR package over the regular package to have faux transparency. I remember at some point that package was discontinued or outdated and didn't build anymore or whatever and then I settled apparently on the one mentioned in the first post.
Are these patches - for example from rxvt-unicode-truecolor-wide-glyphs - even still needed, or is all of that included in the regular rxvt-unicode package from extra nowadays anyways?

Re: [solved] urxvt and aterm don't show characters correctly

Literal "`" would be ASCII anyway and w/ your findings (fwwi, I use the same set of patches plus the sixel patch) it's more likely that the version you compiled has a bug or completely lacks any terminfo?

The wideglyphs patch should result in more lenience regarding the glyph box (mostly relevant for fallback fonts) - the main reason I build a custom urxvt is to enable pixbuf what allows me to have identifying backdrops for special windows (eg. mutt etc)

Re: [solved] urxvt and aterm don't show characters correctly

Something must be off still...

rxvt-unicode-pixbuf-sixel-patched doesn't build for me and guess where it fails: terminfo

output of yay -S rxvt-unicode-pixbuf-sixel-patched

"The permission denied" strikes me, because the directory r is 755 and the terminfo entries are 644.

$ lsd -al /usr/share/terminfo/r/

Re: [solved] urxvt and aterm don't show characters correctly

rxvt-unicode-pixbuf-sixel-patched

I just added the sixel patch to rxvt-unicode-truecolor-wide-glyphs
The terminfo failures are b/c of https://bugs.archlinux.org/task/78578 - rxvt-unicode-truecolor-wide-glyphs has a workaround for that.

Re: [solved] urxvt and aterm don't show characters correctly

You're a genius! I just assumed it must've been my terminfo that was causing this because it fit the picture so nicely.
I patched the truecolor-wide-glyphs with the sixel patch and it's working great.
Thank you all for your help!
