I've installed Telegram on my Ubuntu 18.04. My system is updated and everything is updated. When I try to open telegram, for Persian texts, it uses a very weird monospace like font. I've tried writing the following to the ~/.fonts.conf file but it doesn't take effect.

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
        <match target="pattern">
                <test name="lang" compare="contains">
                        <string>az</string>
                </test>
                <test name="family">
                        <string>sans-serif</string>
                </test>
                <edit name="family" mode="prepend" binding="same">
                        <string>Noto Naskh Arabic</string>
                </edit>
        </match>

        <match target="pattern">
                <test name="lang" compare="contains">
                        <string>az</string>
                </test>
                <test name="family">
                        <string>serif</string>
                </test>
                <edit name="family" mode="prepend" binding="same">
                        <string>Noto Naskh Arabic</string>
                </edit>
        </match>
</fontconfig>

When I run telegram from the terminal I get the following log:

Gtk-Message: 21:37:50.085: Failed to load module "canberra-gtk-module"

Does anyone have any idea how to solve this problem, I've checked the other topics over the net and they mostly consist of changing the fonts configuration file, but I think there might be sth wrong with apparmore.

There is similar topic in askubuntu question about telegram and its bad support for Persian language fonts.

A good news is that Telegram on newer release add default support to Persian with adding Vazir font family.

For you I suggest to remove telegram-desktop package if install with Ubuntu repository and download the latest one from official website to use latest update of telegram.

apt purge telegram-desktop

If you prefer more info on installing telegram in this method please read my answer on Iranian UBUNTU Community.
