Problem with xmpp clients pidgin and dino - No letters

Hi I try to run jabber on my parrot, I installed pidgin first and there is no letter, when run the program, then I install dino xmmp client and there is same situation with letter…See pic below from two clients.

Most of programs have same “letters” like gimp, bluetooh manager, chess game etc etc…
Any clue why this happens? it’s annoying.

Thanks prada

its font compatibility issue
try either changing the fonts or re-configuring font configs
for that do
sudo dpkg-reconfigure locales
sudo dpkg-reconfigure fontconfig-config
