This  has  already been  done  in  1.7b.  ALL characters  are  considered
'SPECIALS',  except   those  that   obviously  aren't  (like   A-Z  0-9).
Technically, there  is no question:  X'6A' is  neither one of  the listed
special characters  nor an EBCDIC  control character, and thus  should be
accepted. Unfortunately  the mailer  thinks otherwise,  so it's  safer to
quote everything and tell users that the reason their name must be quoted
is that it contains non-US characters -  they should be happy it works at
all, after all.
