Allow Spaces in Character Names.

I know it's probably too late to change the backend for PoE 1 at this point, but for PoE 2, please allow spaces in character names. This will allow us to give a character a "last name" or something to minimize the number of "This Name is Already Taken" messages we have to sit through every new league.

Guild Wars (1 and 2) did this back in 2006 to solve this very issue, and it works super well. It will also allow people to maintain a sort of "identity" across leagues.
