Você pode permitir emojis em nomes de usuário

[gerhard (Gerhard Schlager)]

No, it’s not possible to allow Emojis within usernames. They aren’t considered a letter.

By default Discourse permits letters (Ll / Lm / Lo / Lt / Lu ), marks (Mc , Me , Mn ) and numbers (Nd , Nl , but not No ). The setting can restrict those characters, but it’s not possible to allow additional characters.
