I wish it was allowed to have persian letter usernames maybe even symbols as usernames it looks really cool and increases the username pool as well.
You won’t get non latin usernames anytime soon. But you can change the display name using non latin charactets
Display Name field. You can use whatever you want. Even emojis. The feature is already in Lemmy; but not every instance has it available. Lemmy.World does use it, though.
I see Arabic used from time to time
In usernames?
This user’s name is displayed in Arabic, although the characters in the URL are Latin.
Is it possible to make it in other than latin?
have you ever seen a non-latin char url, ever?
the fedivere is incredibly url/dns dependent. labels/content can be any language (mbin uses weblate to allow for dozens off languages) but the underlying urls that control everything prolly require latin chars
