I've seen a few ships in game with alternate lettering such as cyrillic letters and have wondered:
A) Is it allowed in Discovery?
B) If so, how is it done?
I tried to find a way to do this as far as using Umlauted vowels in Rheinland ship names, but couldn't make it work.
I see them used by the game in base names and NPC names, so apparently there is a way to use them?
1.4 - All character, faction, ship or station names must be easily readable and roleplay appropriate. The use of profanity, country tags, memes, pop-culture references, non-English letters, or excess symbols is not allowed. For examples, see here.
