/**
 * Strings in methods inherited from nsIURI, which are using XPIDL
 * |string| types, are expected to be UTF8 encoded. All such strings

 * be UTF8. It's important to remember that attributes can not be UTF8,
 * they can only be of a limited subset of ASCII (see RFC 2251).
 *
 * Currently we deal with this encoding using two little helper methods
 * in the nsILDAPService interface, |UTF8toUCS2()| and |UCS2toUTF8|,
 * which are both scriptable. This will hopefully go away once a real
 * solution is implemented, see bug 84186 for more details.
 *
 * FYI, ASCII is a subset of UTF8.
