[cabfpub] RFC5280-related Ballot - For Discussion

[Peter Bowen]

Huh?  Why would you need to use UTF8String?

IA5String allows underscore characters, as it is a super set of X3.4 (1968).  It also allows $, %, &, *, +, @ and many other characters.  

Were you maybe confusing IA5String with PrintableString, where the latter does not allow underscore, @, etc?
