This is all so confusing and frustrating. I've Googled and found tons of answers. However, not the right one.
I am not a Sigil expert. I have an ePub book that has Mangal fonts to show Hindi. It shows correctly on some devices and ???? on other. I read that if I embed those fonts in my ePub file, it will show correctly on ALL devices. If I am right, all I want to do is add Mangal fonts to my fonts folder (or am I totally wrong?), save my ePub file.
Is this possible? Can anyone give me a step-by-step without sending me to a link? Please.
