Cannot be used with urxvt

[Mikaela]

Related config:

URxvt*font: xft:DejaVu Sans Mono:pixelsize=11, xft:unifont:pixelsize=11, xft:Andale Mono:pixelsize=11, xft:Inconsolata:pixelsize=11, xft:FontAwesome:pixelsize=11

Error:

urxvt: unable to calculate font width for 'FontAwesome:slant=0:weight=100:pixels
ize=11:minspace=True', ignoring.

Version: 4.0.0~dfsg-1

[tagliala]

Any hints on what we can do to fix this?

[Mikaela]

No, sorry. I only tried with that config and always when Awesome char comes, I get that error in the terminal where I executed urxvt to see errors.

[andornaut]

I'm also hitting this issue. You might find it easier to reproduce by starting urxvt with:

urxvt -fn "xft:Font Awesome"

[rebasar]

Can confirm. On Debian Wheezy with backports repo enabled. Relevant package versions:

fontconfig: 2.9.0-7.1
libxft2: 2.3.1-1
rxvt-unicode: 9.15-2+deb7u1

reb@terra:~% fc-list| grep Awesome
/home/reb/.fonts/fontawesome-regular.ttf: FontAwesome:style=Regular
reb@terra:~%

If you need any other information, I will be happy to provide.

[tagliala]

check other icon fonts (like glyphicons) and let us know if you experience the same issue

[rebasar]

Hi,

I don't have glyphicons installed (due to licensing issues) but I do have Pomodoro, Trellicons and Octicons installed and I get the same issue with those too.

[tagliala]

@rebasar thanks for the feedback. Maybe there are issues with the PUA?

Since this is not related to fontawesome I need to close this request but feel free to comment

[Anachron]

@tagliala I also have this issue and would like it to be resolved. =)
What information do you need further to dig into it?

Edit:

 $ fc-list | grep awesome
/usr/share/fonts/TTF/fontawesome-webfont.ttf: FontAwesome:style=Regular

$ sudo pacman -Qe | grep font
ttf-font-awesome 4.5.0-2

inside .Xresources

URxvt.font:             xft:Droid\ Sans\ Mono:pixelsize=12:Regular,xft:Font\ Awesome:antialias=true:pixelsize=12

[tagliala]

@Anachron sorry but I have no hint on how to solve this.

Please try the .otf version of fontawesome or other webfonts (glyphicons, material design icons, elusive icons, octicons, ionicons...).

If also other webfonts have the same issue so this is probably something that does not depend on fontawesome

[Anachron]

It works with powerline symbols for example. 👍

[pinpox]

I'm still having this exact issue. Has there been found a solution somewhere?
Using the rxvt-unicode-patched version from the AUR (Arch linux)

[shellkr]

I have it working when using xft:SauceCodePro NF:pixelsize=9 as a fallback in ~/.Xresources. The font can be found at https://github.com/ryanoasis/nerd-fonts.

[blueyed]

This is a bug in rxvt-unicode, which only looks at chars that are not included in the font when determining its width. The fix is to also consider spaces in this process: http://lists.schmorp.de/pipermail/rxvt-unicode/2016q4/002308.html.

[blueyed]

But rxvt-unicode will still have problems with wide glyphs, with a width of 1 cell according to wcwidth.
Check out ryanoasis/nerd-fonts#92 (comment) and the comments around it.

[blueyed]

This issue will show itself when starting rxvt-unicode from another terminal, where you should then see a message like the following when a glyph from the font is attempted to be used:

urxvt: unable to calculate font width for 'FontAwesome-4:slant=0:weight=200:minspace=True', ignoring.

[ghost]

@blueyed What is that patch supposed to fix? I have FontAwesome as a fallback font in urxvt and I applied that patch (successfully) to rxvtfont.C, but I still can't get it to work.

[blueyed]

@poisonby
There are other issues you might run into now, e.g. that urxvt considers the glyphs to be too wide.
Try some glyphs that are narrow, and more likely to fit into a cell.

[ghost]

@blueyed

You're right, some characters seem to work (like \uf07d), though most doesn't work. Is there no way to get all characters to work, or is the only option to switch to another terminal emulator?

Thanks.

[blueyed]

I have two hacks in this regard (see my fork). Not much love for this by default.. ;)
blueyed/rxvt-unicode#1

Using another approach locally since a while.

[ghost]

@blueyed

I actually compiled and installed it by messing with ABS, didn't see that you had a README there so it appears I missed a few build options. I'm running Arch though so I'll try your PKGBUILD. =) I'll update if it works.

[ghost]

@blueyed

It worked! Thanks for the help. An effect from this though is that I had to switch URxvt.letterSpace from -1 to -2 to set the correct spacing. The characters seem to show up regardless though. =)

[guest73]

Hi @blueyed, I tried your hack and it kind of worked for me. The only problem is, I am used to rxvt-unicode-256color. With your patched version I cannot make it to use 256 colors. Can we have the patch for 256color version?

[blueyed]

@guest73
Which one have you tried?
I recommend my first approach: https://github.com/blueyed/PKGBUILD-rxvt-unicode-wide.
It is available in AUR: https://aur.archlinux.org/packages/rxvt-unicode-cvs-patched-wideglyphs/

[guest73]

@blueyed
Thanks for responding. I used the one from here https://github.com/blueyed/rxvt-unicode/blob/wcwidth-hack/README.md. But the problem is I am on Debian and I am not so skilled in all this mumbo-jumbo. Debian has 2 packages rxvt-unicode and rxvt-unicode-256color. I think your patch was for the first one. I think the first one has something like max_colors#88, max_pairs#7744 and the second one max_colors#256, max_pairs#32767 according to terminfo but I am really not sure what it is all about.

[blueyed]

So you are building your own .deb then?
You should use the patch(es) from https://github.com/blueyed/PKGBUILD-rxvt-unicode-wide then.
When building from source (or in general), the PKGBUILD might come in handy for guidance: https://github.com/blueyed/PKGBUILD-rxvt-unicode-wide/blob/master/PKGBUILD

It is pretty offtopic here though, so let's stop there.

[dhruvinsh]

well if anyone still looking for solution, Nerd patched font did work for me without any issue.

my .Xresources file has this config:

URxvt.font: xft:SF Mono:size=12,xft:Inconsolata Nerd Font Mono:size=11 
URxvt.letterSpace: -1 

main font is SF Mono and fallbacks to Nerd patched font.
