windows has a weird khmer font (unicode), this causes issue when you have telegram install on your computer and some of your group chat using khmer language,
the problem: font appear to small for unicode.
to temporary resolve the issue,
you need to make change in windows registry under FontSubstitutes --> MS Shell Dlg 2 with the value of new khmer font ex: Khmer OS
this script will do all of that for you.
install pre-req
pip install winregistry
and on line 20 of main.py file choose whatever font name you prefer
set_run_key("MS Shell Dlg 2", "Khmer OS")
run the your py file, make sure your terminal/cmd is running as administrator.
python3 main.py
and restart your computer.
