I'm considering expanding one of my fonts to add additional Latin language support and Cyrillic support. The Latin language character adds would cover most Latin languages (I like using Underware's Latin Plus checker, and nearly all of these languages would be supported).
My question is about Cyrillic. I'm not very familiar with it and I know Glyphs app has the built-in "Basic" and "Adobe Extended" character sets. Do you think if I just include the Basic characters it would provide enough support for those using Cyrillic and justify the "Pro" tag with an increased price. Or do you think the Adobe Extended set would be necessary?
Thanks for your thoughts!
