Here are some ones for every letter of the alphabet! These are from different languages, symbols that look like letters, emojis, etc. etc. Some of these look practically identical (ex: M versus Μ) but I promise the are different. 
If I missed anything, be sure to point it out! ^^
Note: [name_m]Don[/name_m]’t forget that you can just write [name_f]Zoe[/name_f] as Żøę & the problem is solved for some computer systems, by the way. 
But don’t forget that others can see through that!
