I wasn't able to edit my title/info anymore but I did add other special characters onto the explanation yesterday while I still could. You are right tho, haha. Thanks for the idea <3 

I do think that is indeed the problem, perhaps there is a way around this? While I am no coder myself and have little knowledge on the subject I do believe there should be a way to avoid this (somehow) Or otherwise, another option could be to not include this into the URLs. Again, I have little knowledge about this stuff, haha. 

Exactly, MoMs are able to use some special characters in the Admin but even then I think we should be able to do it ourselves when creating a character/changing your character's name. Dashes sadly cannot be added in admin as far as I am aware. It would be nice if we could use them from the get-go
