Comment:

 I wasn't able to really debug this yesterday, so here's more.

 The issue seems to actually be in wpmu_create_user() in wpmu-functions.php
 line 1148.

 {{{
         $user_name = ereg_replace("[^A-Za-z0-9]", "", $user_name);
 }}}

 This causes admin added usernames using Site Admin > Users to be
 restricted to alphanumeric with no filter or action to change behavior.

 I don't know if I am missing the intent of this restriction.
