I'm working on my debut font. Just about to finish standard latin glyph. And I'm thinking to expand it to multilingual. The problem is, I don't understand what glyph/unicode to design in order for my font to support multilingual.
I tried to observe other fonts about multilingual support, and it turns out not every the unicode in latin extended A, B etc. is assigned with some design. In other words, there is some blank unicode in latin extended A, B, etc. So it doesn't help me understand which unicode range shall I design to support multilingual.
Can anybody explain me the unicode range to design in order for my fonts to support multilinguals? Or maybe is there some concept/keywords shall I learn so I can understand about multilingual support?
