Arabic font style isn't good in Ubuntu 18.10 development branch

[YousefSaber]

English font style is good but Arabic font style isn't good it's some how bold which I don't like tried to install GNOME tweaks to change the font but I couldn't succeed

this is the desired Arabic font style which was present in Ubuntu 18.04.1 on telegram

but this is the Arabic font style in Telegram which I don't like

Operating system:

Ubuntu Cosmic Cuttlefish (development branch) using GNOME shell v3.30 as desktop environment

telegram v1.3.14 installed from a tar.xz from your official website ( to get updates quickly ) https://desktop.telegram.org/

please make sure that this issue will be avoided in the official final release of Ubuntu 18.10

That's the settings from custom fonts.conf:

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
    <match target="font">
    <edit mode="assign" name="antialias">
        <bool>true</bool>
    </edit>
    <edit mode="assign" name="hinting">
        <bool>true</bool>
    </edit>
    <edit mode="assign" name="hintstyle">
        <const>hintslight</const>
    </edit>
    <edit mode="assign" name="lcdfilter">
        <const>lcddefault</const>
    </edit>
    <edit mode="assign" name="rgba">
        <const>rgb</const>
    </edit>
    </match>
</fontconfig>

You can put it into ~/.config/fontconfig/conf.d/99-default.conf and your system will use the anti-aliasing settings from custom fonts.conf

Here is how I fixed this issue:

• Close Telegram
• Create directory: ~/.fonts
• Add a font with its different weights [I used Vazir]
• Create file: ~/.fonts.conf and add these lines to it:

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
 <match target="pattern">
  <test name="family" qual="any">
   <string>sans serif</string>
  </test>
  <edit mode="assign" binding="same" name="family">
   <string>Vazir</string>
  </edit>
 </match>
 <dir>~/.fonts</dir>
</fontconfig>

• Clear font caches: fc-cache -f -v rm -r ~/.cache/fontconfig_11
• Now open Telegram :)

this doesn't work with normal binaries from telegram website on Kubuntu 20.04 Beta.

i created ./fonts/fonts.conf and added these lines to it and installed vazir fonts to ./fonts. any ideas?

@ilya-fedin ?

~/.config/fontconfig/conf.d/99-default.conf

@ilya-fedin thanks.i forgot to write the font name with capital letter and that was the problem.now it works can i also change english fonts to something else like Open_Sans?

[ilya-fedin]

no, you can't without patching the sources

[TheHolyLoli]

@ilya-fedin what is the default font?does it by default use open_sans or noto_sans in my case?(im on kubuntu and default system font is noto sans) im confused because to me it seems a little different than windows version binary

[ilya-fedin]

Open Sans

I'm going to close this issue after nearly more than a one and half year of opening since the issue is fixed on Ubuntu 20.04 with telegram version 2.01 in both the executable application and snap app ( didn't test the flatpak app ) I'll reopen this issue if it surfaced again.
