Is it used anywhere, by anyone? It's current meaning is indeed *any* character, valid or not. Reason I ask is that we are contemplating a "valid" class, that can be used to reject candidates containing characters not valid for the chosen codepage. The ?v name came to mind but it's already taken. Now I noticed the ?z and I can't really think of any use for it - but if we modify it to mean "match any *valid* character" I see many uses. Maybe it was meant for PP stuff, much like the ':'. Failing to hijack ?z, any other suggestion for a better letter? magnum
