Not really (but it depends).  The 'portal_registration' tool is
responsible for enforcingthe site's policies on allowable user IDs;  the
canonical way to change the policy is to replace that tool with one
which knows your policy.

If you allow user IDs to contain charachters which aren't legal in URIs,
then some users' member areas will have to be escaped;  you might need
to customize skins for this, as the current ones may assume that user
IDs are "URI-safe".
