In other news. How many Hungarians are ever going to be writing in Thai?

EDIT: Used the wrong quote here. Fixed.

Communities like mathematicians are more to blame for that than Unicode.

Unless maybe you want a Latin script/Cyrilic/Greek etc. unification (for the relevant characters).

I guess that would work in the same way that rot13 encoding (like spoilers) does; not worth to decode since only a few specially interested people do it. But it’s not like it’s difficult if anyone puts some effort in. But yeah, such nerdisms can definitely be useful as long as they remain a subcultural thing (presumably always will be).
