As for now I've managed to have properly working Telegram with correct dialog windows and fonts in Debian Buster with this workaround:

  1. Create file ~/.config/tgfonts.conf
<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
    <description>Telegram-specific configuration file</description>
    <dir>/usr/share/fonts</dir>
    <dir>/usr/X11R6/lib/X11/fonts</dir> <dir>/usr/local/share/fonts</dir>
    <dir prefix="xdg">fonts</dir>
    <match target="pattern">
    <test qual="any" name="family">
        <string>mono</string>
    </test>
    <edit name="family" mode="assign" binding="same">
        <string>monospace</string>
    </edit>
    </match>
    <match target="pattern">
    <test qual="any" name="family">
        <string>sans serif</string>
    </test>
    <edit name="family" mode="assign" binding="same">
        <string>sans-serif</string>
    </edit>
    </match>
    <match target="pattern">
    <test qual="any" name="family">
        <string>sans</string>
    </test>
    <edit name="family" mode="assign" binding="same">
        <string>sans-serif</string>
    </edit>
    </match>
    <cachedir>/var/cache/fontconfig</cachedir>
    <cachedir prefix="xdg">fontconfig</cachedir>
    <cachedir>~/.fontconfig</cachedir>
    <match target="font">
    <edit mode="assign" name="antialias">
        <bool>true</bool>
    </edit>
    <edit mode="assign" name="embeddedbitmap">
        <bool>false</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>
  1. Modify telegram .desktop file (~/.local/share/applications/telegramdesktop.desktop AND/OR /usr/share/applications/telegramdesktop.desktop) to:
[Desktop Entry]
Version=1.3
Name=Telegram Desktop
Comment=Official desktop version of Telegram messaging app
Exec=env FONTCONFIG_FILE=~/.config/tgfonts.conf /opt/telegram/Telegram -- %u
Icon=telegram
Terminal=false
StartupWMClass=TelegramDesktop
Type=Application
Categories=Network;InstantMessaging;Qt;
MimeType=x-scheme-handler/tg;

No crashes, no error messages, proper fonts in app, in tray icon, in send file dialog.

Have you see the log? It seems not a same problem. Telegram works fine before I upgrade fontconfig to 2.13.0.

@codeplayer2org sorry.

After updating to 1.2.14-2, I no longer experience this issue.

AJubatus picture AJubatus on 25 Mar 2018

As I stated here, https://www.reddit.com/r/archlinux/comments/873b6i/fontconfig_213_crashes_telegram/
I do have this problem too, i have fontconfig 2.13.0+10+g58f5285-1 in archlinux and tested telegram 1.2.14 and 1.2.15, same output

Akrai picture Akrai on 26 Mar 2018

@Akrai did you try telegram-desktop package from Arch Linux repo? I have same version of fontconfig but with telegram-desktop 1.2.14-2. No issue, only this in output:
QApplication: invalid style override passed, ignoring it.
QObject::startTimer: Timers cannot have negative intervals

d0tfile picture d0tfile on 26 Mar 2018

@d0tfile i just tried it and nothing, same error

Akrai picture Akrai on 26 Mar 2018

export FONTCONFIG_FILE=/etc/fonts/ solves the problem for me.

ghost picture ghost on 27 Mar 2018

So dealing with the FONTCONFIG_FILE=/etc/fonts/ env, seems like kde dont like that env as it makes all the characters get render as missing character symbol, telegram runs fine but if you open the file picker, which uses the kde one, then all characters in the file picker are missing
If you set it as global env in the kde env folder, then all the DE is bugged with missing characters, so as i can see, as telegram is the only program with this bug (as i know), it seems it is a problem of telegram looking for the fontconfig file in a maybe deprecated location that still exists but is no longer in use by any other programs?

The app in official Arch repo hasn't this error. It works fine.

ghost picture ghost on 27 Mar 2018

@RobertoPerico you are right, i didnt know there is an official package in arch, i tried in the other comment to install the aur one
so yes, the official one does work

Akrai picture Akrai on 27 Mar 2018

@Akrai By official you mean officialy from who?

john-preston picture john-preston on 27 Mar 2018

@john-preston the official package in the arch repo, https://www.archlinux.org/packages/community/x86_64/telegram-desktop/

Akrai picture Akrai on 28 Mar 2018

@Akrai It is not from the Telegram team so I'm wondering what "official" means here.

john-preston picture john-preston on 28 Mar 2018

@john-preston i didnt said official telegram package but official package in arch meaning that it is in the arch repo, not in aur

Akrai picture Akrai on 28 Mar 2018

Yeah, I kinda prefer to not use the arch-linux packaged version, since it doesn't update as much as I'd like.

That being said, the export FONTCONFIG_FILE=/etc/fonts/ fix that @RobertoPerico gave works for me - it seems like this is also necessary on i3 since I wasn't exporting it anywhere before.

PandorasFox picture PandorasFox on 28 Mar 2018

Relevant to say:
exporting FONTCONFIG_FILE to /etc/fonts/ does not fix it 100%. CJK fonts break, all the characters get replaced by squares.

1.2.15
same error...

ireflux picture ireflux on 31 Mar 2018

I think the bug doesn't belong to Telegram, since i've tried to download the .tar on Fedora 27 and the problem didn't show up. So i think it's a fontconfig bug.

ghost picture ghost on 31 Mar 2018

@RobertoPerico Yeah, you are right. I rolled back the fontconfig and it worked fine, but it brought some other problems, so I reinstalled the latest version...
update:
thanks, your answer export FONTCONFIG_FILE=/etc/fonts/ solved my problem.

ireflux picture ireflux on 31 Mar 2018

In fact, export works with any existing directory, e.g.
mkdir testing
export FONTCONFIG_FILE=/home/user/testing/
works fine for me. Looks like in this case Telegram does not try to use system config from /etc/fonts/fonts.conf but use some default configuration and that's the reason why it works fine.

Empty variable also works fine: export FONTCONFIG_FILE=

This worked for me on arch linux:

pacaur -S downgrader
downgrader fontconfig --> select 2.12.6
mkdir fc
cp -r /etc/fonts/* fc
pacaur -S fontconfig --> (upgrade again)
cp -fr fc/* /etc/fonts/

As for now I've managed to have properly working Telegram with correct dialog windows and fonts in Debian Buster with this workaround:

  1. Create file ~/.config/tgfonts.conf
<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
    <description>Telegram-specific configuration file</description>
    <dir>/usr/share/fonts</dir>
    <dir>/usr/X11R6/lib/X11/fonts</dir> <dir>/usr/local/share/fonts</dir>
    <dir prefix="xdg">fonts</dir>
    <match target="pattern">
    <test qual="any" name="family">
        <string>mono</string>
    </test>
    <edit name="family" mode="assign" binding="same">
        <string>monospace</string>
    </edit>
    </match>
    <match target="pattern">
    <test qual="any" name="family">
        <string>sans serif</string>
    </test>
    <edit name="family" mode="assign" binding="same">
        <string>sans-serif</string>
    </edit>
    </match>
    <match target="pattern">
    <test qual="any" name="family">
        <string>sans</string>
    </test>
    <edit name="family" mode="assign" binding="same">
        <string>sans-serif</string>
    </edit>
    </match>
    <cachedir>/var/cache/fontconfig</cachedir>
    <cachedir prefix="xdg">fontconfig</cachedir>
    <cachedir>~/.fontconfig</cachedir>
    <match target="font">
    <edit mode="assign" name="antialias">
        <bool>true</bool>
    </edit>
    <edit mode="assign" name="embeddedbitmap">
        <bool>false</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>
  1. Modify telegram .desktop file (~/.local/share/applications/telegramdesktop.desktop AND/OR /usr/share/applications/telegramdesktop.desktop) to:
[Desktop Entry]
Version=1.3
Name=Telegram Desktop
Comment=Official desktop version of Telegram messaging app
Exec=env FONTCONFIG_FILE=~/.config/tgfonts.conf /opt/telegram/Telegram -- %u
Icon=telegram
Terminal=false
StartupWMClass=TelegramDesktop
Type=Application
Categories=Network;InstantMessaging;Qt;
MimeType=x-scheme-handler/tg;

No crashes, no error messages, proper fonts in app, in tray icon, in send file dialog.

Let's move discussion to the #4240

@phpony thanks! Just trying to get that into gentoo
https://github.com/gentoo/gentoo/pull/10055

btw, the built-in updater will destroy your .desktop changes on every update

@phpony 🤔 Perhaps this could be included as an in-app solution to that problem.

Hi everyone, just wanted to post that this is still happening on Ubuntu 18.10 (Was not happening in 18.04) using Telegram 1.4.3 What I did was a combination of things here and basically this:

Created the file mentioned by @phpony and the XML information without the description line (line 4):

  1. Create the file at ~/.config/tgfonts.conf

nano ~/.config/tgfonts.conf

Then put this information in it

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
    <dir>/usr/share/fonts</dir>
    <dir>/usr/X11R6/lib/X11/fonts</dir> 
    <dir>/usr/local/share/fonts</dir>
    <dir prefix="xdg">fonts</dir>
    <match target="pattern">
    <test qual="any" name="family">
        <string>mono</string>
    </test>
    <edit name="family" mode="assign" binding="same">
        <string>monospace</string>
    </edit>
    </match>
    <match target="pattern">
    <test qual="any" name="family">
        <string>sans serif</string>
    </test>
    <edit name="family" mode="assign" binding="same">
        <string>sans-serif</string>
    </edit>
    </match>
    <match target="pattern">
    <test qual="any" name="family">
        <string>sans</string>
    </test>
    <edit name="family" mode="assign" binding="same">
        <string>sans-serif</string>
    </edit>
    </match>
    <cachedir>/var/cache/fontconfig</cachedir>
    <cachedir prefix="xdg">fontconfig</cachedir>
    <cachedir>~/.fontconfig</cachedir>
    <match target="font">
    <edit mode="assign" name="antialias">
        <bool>true</bool>
    </edit>
    <edit mode="assign" name="embeddedbitmap">
        <bool>false</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>

Save it then run this

export FONTCONFIG_FILE=~/.config/tgfonts.conf

Now run Telegram from the terminal. But am waiting for a default fix. Thank you.

Here is how I fixed this issue for Persian on:

  • Fedora 29
  • Debian 9+ (including ubuntu 18.10+)
    with GNOME Shell 3.30.2 (3.28+)

1 - Close Telegram
2 - Create directory: ~/.fonts if not exists
3 - Add a font with its different weights [I used [Vazir](https://rastikerdar.github.io/vazir-font/)]

copy Vazir.ttf Vazir-Bold.ttf Vazir-Light.ttf Vazir-Medium.ttfto your ~/.fonts folder

4- 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>

5 - open Telegrams font configuration file ~/.local/share/TelegramDesktop/tdata/fc-custom-1.conf
6 - Comment out all <dir> and <cachedir> entries there (simply wrap them between <!-- and -->).
7 - Remove old caches by rm -r ~/.cache/fontconfig_11
8 - Clear font caches (for sure):
fc-cache -f -v

Now open Telegram ツ
