rsalz> There are two reasons why users enter "illegal" passwords now, and by 
now requiring them to make it explicit we can (a) check only for ASCII on 
current inputs; (b) make them thing about what they're doing and require them 
to specify; (c) set the expectation that something will change in the future.

A variant is to check if the 8bit string can be decoded as a UTF-8
string and warn the user that such string is going to get screwed.
