[BUG] Issue wait accents in nicknames

[vindoze]

Describe the bug
When a player's nickname contains one or more characters with an accent (such as é, è, ë, à, ï, ù)
We hear the player as if he hadn't moved from his first spawn and that player hears us as if he hadn't moved from spawn.

To Reproduce
Steps to reproduce the behavior:

1. Set your in-game nickname to 'vïndoze' (with a ¨ on the i)
2. Join a private game
3. Connect to the chat with the exact same nickname (vïndoze)
4. The chat won't register your movements

Where are you using the proximity chat?:
