Thanky you very much Roshan.
Now your description is very comprehensive even for non-experts.
It worked perfectly, I didn’t have to clear the cache. And the Czech letters look much nicer 🙂
I’m looking forward to you tutorial (video or written in details). Sure, many users here will appreciate it.
Could you include a note about how to add and integrate a different font there (e.g. a fancy font for headings) and how to use the “secondary” / backup fonts?
In fact I must admit Andre was right with his idea not to blow up the themes with unnecessary things. With you help / tutorial, I (anybody) can upload just a font I’d like to and in my language.
