There are 2 solutions in the X.400/88 standard to the character set problem
in O/R names.
1) Allow TeletexStrings in O/R name attributes
TeletexStrings allow ISO-IR-87, which is a Japanese character set.
(they probably had a man on the comittee...Greek and Arabic are still out)
2) Allow Directory Names instead of O/R names to be used in submission.
This allows looking up the "real" name from X.500.
(why standardize one solution when you can standardize two :-)
In both cases, you can see the hand of ADMDs trying to protect their
previous investment: whenever an O/R name is passed across an international
boundary, it is supposed to have all attributes represented in Printable
(that is, USASCII without some characters) IN ADDITION TO other forms.
People are thinking now that an address should be for machines, not people.
I would not like to have to consider Chinese (or Norwegian) characters
for my routing tables, even though my son's name cannot be written in ASCII.
As for uniqueness, this is a local matter.
Often, use of OUs will be sufficient.
But I know of an organization where two people with the same name worked in
the same OU; one of them got an arbitary middle initial.
