valid username in federation

[Former user]

i have read this : The username is limited to printable UTF-8 with whitespace and the following characters excluded: <*,>' - Stellar Developer Doc but i do not understand what exactly are UTF-8 characters as i know that some letters that are not a-z are included in utf-8. can you show me an example for regex that uses their limits? Thanks

I meant unicode characters. So anything is valid, in any language, outside of the stated characters.

Example of valid usernames:

• francois
• françois
• フランソワ
• 山田太郎
• 최민식
• อุรัสยา-เสปอร์บันด์

Nothing to add to this.
