Un- Readable Characters for Installed Applications.

Hello Team,
I have installed Latest Parrot OS (4.9) Security Edition. But now i am facing issue of unreadable characters on some application interface.
.
I was advised to change fonts on Facebook Group but that did not work out

Application Interface is totally unreadable which causes more issue.

Please assist and find the screenshot for the same.

Well its font compatibility issue
you can change to another font or try re-configuring the font cache
for that
sudo dpkg-reconfigure locales
sudo dpkg-reconfigure fontconfig-config
and log out and log in or Restart
