Comment(by cnorris23):

 As apeatling stated, the slug is passed through sanitize_title(). The
 problem with "<oOoOoOoOoO(°_°)", and Edz's original example of "?", is a
 reflection of the limitations of sanitize_title() (more specifically PHP's
 strip_tags()). It's liberally designed to strip HTML and PHP tags, which
 is why "?" is stripped out. In the case of "<oOoOoOoOoO(°_°)", the issue
 is that there's no closing bracket. If you changed "<oOoOoOoOoO(°_°)" to
 "<o>OoOoOoOoO(°_°)", "o" within the brackets, and the brackets themselves,
 would be removed, but the rest would remain. WP utilizes the
 $fallback_title parameter of sanitize_title() to account for this
 scenario. WP uses the post_id as the fallback title, and BP could,
 respectively, use group_id.
