I had some reports from members, that while creating a character, using accents, mostly in french, the character is rather created and not attached to the user, or simply, isn’t detected while you want to join an Event. Could it be a UTF-8 issue?
Can you please post some example character names? In theory once the character assigned to the user the name shouldn’t matters.
So in those cases as a workaround you can assign character to the user manually on the backend (editing the character).
In 0.7 I’ve changed the method how characters are connected to users, I hope that will fix your problem, but I need more information to reproduce that error.
Alright, I’ll ask the person that actually found the possible reason to this bug, to try on the 0.7 version. Which I did installed now. Will let you know.
