The default font for Bengali language is Lohit Bengali. But it is ugly and I don't like this font. So I want to replace it with a font called Bangla.
Or, I want to set Bangla as default Bengali font systemwide instead of Lohit Bengali. I'm not asking about how to change it on Chrome, Firefox, LibreOffice etc. I want to change the system font. I can change the English font with Gnome Tweak Tool. But there is no option for native language fonts.
