so whether we should allow spaces is problematic. Certainly if we allow them in 
the input fonts then we should replace them in our output PDF so they obey the 
rules; then we likely are breaking someone's copyright etc etc etc.

Any real experts out there please pipe up. Last time this sort of thing came up 
was when we had the not subsettable flag set. I think we agreed that even though 
our software could subset we ought not to if it was specifically forbidden.
