Comment (by avryl):

 Is this possible considering that usernames are used in urls like author
 pages? It's also worth noting that plugins might rely on the fact that the
 username is alphanumeric (e.g. P2's @mentions).

 This is related to allowing non-ASCII post slugs and IDN support (see
 #10690 and #10298).
