I think it's better to have minimal escaping on the wire as
DNs strings are (too) often presented by UIs as they appear on the
wire (on Unicode capable devices).

I view this as a separate issue.  For LDIF, ldapsearch(1)
escapes non-ASCII strings as we're not sure the user's terminal/printer
is UTF-8 capable.  It would be good to have a flag that caused
minimal-escaping LDIF to be produced (for those who do have UTF-8
capable terminal/printers).
