Answer:

I solved the problem by changing ~/.local/share/TelegramDesktop/tdata/fc-custom-1.conf contents to:

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
    <dir>/usr/share/fonts</dir>
    <dir>/usr/local/share/fonts</dir>


    <dir>/usr/X11R6/lib/X11/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</string>
        </test>
        <edit name="family" mode="assign" binding="same">
            <string>sans-serif</string>
        </edit>
    </match>
    <cachedir>/var/cache/fontconfig_11</cachedir>
    <cachedir prefix="xdg">fontconfig_11</cachedir>
    <cachedir>~/.fontconfig_11</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">

    </edit>
    <edit mode="assign" name="lcdfilter">
        <const>lcddefault</const>
    </edit>
    <edit mode="assign" name="rgba">
        <const>rgb</const>
    </edit>
    </match>
</fontconfig>

and creating a directory named fonts next to the fc-custom-1.conf file and pasting a font named B_Nazanin_YasDL.com.ttf into this directory.

What version of Telegram are using? Check this link https://askubuntu.com/questions/954165/properly-update-telegram — JoKeR, Nov 01 '18 at 23:34
You should try to downgrade your fonts library. Im trying the same. If I succeed I will let you know. — Sepehr GH, Nov 04 '18 at 08:00
Or you should wait for telegram to provide a new version with font support — Sepehr GH, Nov 04 '18 at 08:08

I encountered the exact same problem after upgrading Kubuntu 18.04 to 18.10 !

Trying to figure out what is this weird font, I browsed and found out that Telegram is using KacstArt font (probably because this is the first font in the list when it fetches all system fonts).

I solved my problem by limiting telegram font search-paths into a single isolated folder that contains only my desired font. The procedure goes like this:

There is a font configuration file ~/.local/share/TelegramDesktop/tdata/fc-custom-1.conf open it up.
Comment out all <dir> and <cachedir> entries there (simply wrap them between ).
Add a <dir>[your desired folder]</dir> just after <fontconfig> at the beginning of the file with [your desired folder] being the path pointing to a custom folder containing only your desired font.
(e.g. I created a folder in ~/.local/share/TelegramDesktop/tdata/myfonts then added tahoma.ttf and tahomab.ttf there)
Restart telegram and enjoy.

Putting your desired font in ~/.fonts and commenting out every dir but that might be a slightly faster fix. — Mike Elahi, Jun 28 '19 at 23:16

Here is how I fixed this issue for Persian:

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 :)

Update: Since telegram 1.8.4 there is no fc-custom-1.conf file, so here is another solution (assuming that the telegram binary is in /opt/Telegram/Telegram):

Create a config file for telegram font (path is optional):

touch /opt/Telegram/fonts.conf

and add these lines to it:

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>

 <match>
  <edit mode="prepend" name="family">
   <string>Vazir</string>
  </edit>
 </match>

 <dir>~/.local/share/fonts</dir>
 <dir>/usr/share/fonts/</dir>

</fontconfig>

I used Vazir font, if you want to use another font(e.g. Tahoma) you must change the <string>Vazir</string> to <string>Tahoma</string>.

Modify the telegram .desktop file, which is located at ~/.local/share/applications/telegramdesktop.desktop, to:

[Desktop Entry]
Version=1.0
Name=Telegram Desktop
Comment=Official desktop application for the Telegram messaging service
TryExec=/opt/Telegram/Telegram
Exec=env FONTCONFIG_FILE=/opt/Telegram/fonts.conf /opt/Telegram/Telegram -- %u
Icon=telegram
Terminal=false
StartupWMClass=TelegramDesktop
Type=Application
Categories=Network;InstantMessaging;Qt;
MimeType=x-scheme-handler/tg;
Keywords=tg;chat;im;messaging;messenger;sms;tdesktop;
X-GNOME-UsesNotifications=true
X-Desktop-File-Install-Version=0.23

Place your font in ~/.local/share/fonts.

Just simply remove this file by typing this command in your terminal :

killall Telegram && rm -rf ~/.local/share/TelegramDesktop/tdata/fc-custom-1.conf

Close Telegram app

Copy your font to a directory (for example cp Tahome.ttf /home/alice/Telegram)

vim ~/.local/share/TelegramDesktop/tdata/fc-custom-1.conf

remove all <dir> </dir>

add one <dir>path_to_your_font_dir</dir>

then change all font name to your font name.

My config like:

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>

What Nima said will work, but the best way is to install the snap or the flatpak version of telegram.

first purge your current installation:

sudo apt purge telegram-desktop

then delete the following folder:

sudo rm -rf ~/.local/share/TelegramDesktop

then you can simply do the following :

sudo apt install snapd && sudo snap install telegram-desktop
