[Client] Can't see profile or watch game of player with ¨ (diaeresis) in the name through FL

My pseudo is KäZ with the diaeresis on the letter a. And people in my friend list first see my name as "K" unless I play a game with them.

After playing a game with me, they see my name correctly (KäZ and not K anymore).

the thing is, while seeing my as K, they can't right-click and see my profile, or right-click watch a game i'm playing. they can't invite me through they suggested player because i'm listed as K as well. they need to go in the invite menu and search for my name then invite, or right-click>invite.

The bug occure every time until I play a first game with a friend, that will correct the bug for this one friend but not the others, until next login into the game (me or they)
