My calculation says:
all letters: a-z,A-Z      52
digits 0-9                10
-------------------------------
In all                    62


Then we need 2 more characters. The "non-problem" characters 
tracked down so far are:
'()-+:=,./?

Any of these should be safe. Maybe "." and "," are the mst safe
expected also to be in all other character sets.

I do not have the PEM-DEV right here (well somewhere in that mbox...)
But as far as I remember they did it right. We have just reconveiled
their design  principles....
