I am a great enthusiast who lives in a country using the Cyrillic alphabet. I've always wanted more of the good Latin fonts to support Cyrillic as well - I love both serif and sans serif fonts. For example, I like Gill Sans MT, but as you may know, it doesn't support Cyrillic. I don't know when but a few years ago, Microsoft released the downloadable Gill Sans Nova typeface, which finally supported Cyrillic. But its Cyrillic is awful, really bad. It looks so generic and misses the originality and character of the Latin letters. So I thought: "I could have done it better!" and that's when I decided to learn more about font making. Now I know many things on theory, but I don't know where and how to get some practice. I could use some help. How did you start font making? What software did you use, and where did you learn how to use it? And most importantly - how do you construct letters, for example, letters of sans serif fonts?
-- My biggest dream is to make more fonts usable in countries using the Cyrillic - I want to see great modern typography in my home country and not whatever there is preinstalled on the advertisers' computers!
I would start with Glyphsapp, try the free trial for 30(?) days and see how you like it. It has a clear user manual, many great tutorials, and is just an overall intuitive application to use. I would say the software is the easy part, though.
Then, just start messing about. Try to draw some letters, baring in mind what theoretical knowledge you have, and post the results here for feedback. A couple years later, you might have made a very nice Cyrillic!
To add new glyphs, FL offers the Add Glyphs dialog, where you can add the whole Unicode plus custom glyphs. As a sample, I made a stripped-dow and raw "Gill Something" with all the (empty) Cyrillic glyphs already added. Of course, you must check how each font license handles modifications.
Attached: the Fonts > Add Glyphs menu and the Add Glyphs dialog, plus the font.
By the way, I moved from Windows to Mac just for Glyphs App, and it's really worth it for me.
