mod_rewrite And Member Profiles

Rather wonderfully, one of the members on a forum I'm on has chosen a rather bizarre username:

(D)w C0O\_

That's all fine and dandy, as the vBulletin software allows it. But, because of the way that vBSEO rewrites URLs, members cannot view his profile because it is rewritten thus:

http://www.mysite.com/forums/members/-d-w-c0o-_.html

Is this a known issue?
