Loosen restrictions on usernames by allowing more symbols/characters.
It would be nice if twitch loosened restrictions on usernames since so many are taken and they don't seem to get freed up.
For example allowing usernames starting with symbols (_username), as well as adding more symbols for use, such as '-', '/', '.', '|', '~', and other characters.

In addition to this & the other reply, the name I use in games is Jōtarōゴゴゴ, it would be welcomed and appreciated if we were able to use characters from other languages in our usernames as well as macrons on top of letters (ā, ē, ī. ō, ū).

I would like to use special characters in Display Name.
My current display name is ゆうた敗北 and I want to change it to ゆうた(敗北) or ゆうた「敗北」.
Please allow to use parentheses and Japanese brackets.Note that Display Name is different from Username:

Having the feature to be able to use frequently used special characters like * & + - for example in usernames. Thank you in advance.

I found underscore works but I personally wanted to include a space or a colon but cannot.
