Comment (by boonebgorges):

 Thanks for your help with this so far, wenlujon.

 It's worth noting that, if you're using WordPress Multisite (as you appear
 to be, given your changes in ms-functions.php), the restrictions on login
 characters come from WordPress and not from BuddyPress. See
 https://core.trac.wordpress.org/ticket/17904. BP uses WP's user system,
 and it's unlikely that we would make username requirements less strict
 that WP does in the case of multisite.

 That being said, it's likely that in the case of non-MS, we are being
 overzealous about sanitization of user_login and especially user_nicename
 in various places. Our testing should be focused on non-MS.
