[SOLVED] Some unicode symbols are displaying incorrectly after update

rg_rg · 2018-01-01 06:39:56

After recent update I ran into a problem with unicode symbols in i3bar. Now the symbols are displaying with additional, non-readable characters (see image)
test

Below are relevant configurations:

#~/.i3/config
font pango:Ubuntu Mono 10

#~/.i3blocks.conf
# Backlight
[backlight]
label=
command=xbacklight | awk '{print int($1)"%"}'
interval=10

The label symbol, for example, is displayed with additional '0020' character right after it. So, where to search for the root of the problem? Fontconfig issue?

0x20 is space (" ") f0e4 is private ie. the font can put there whatever it wants.
The numbered box suggests that the used font has no glyph for the value.

Tried another font?
Also check your pacman log on what was actually updated.

And inspect the font resolution

FC_DEBUG=4 pango-view --font="Ubuntu Mono" -t " " | grep family:

try downgrade ttf-font-awesome

rg_rg · 2018-01-01 12:57:15

Didn't think it's font-awesome related, but removing the package also removed the symbols completely. So now I have to research why additional space "0x20" symbol is displayed after each "icon". Also found the related gh issue https://github.com/FortAwesome/Font-Awe … sues/12017.

The solution is to (temporarily) downgrade ttf-font-awesome from AUR, or to use nerd-fonts instead.
