Why do you continue to mis-represent the facts. The Unicode
Standard *does not* have an unlimited repertoire. The repertoires of
Unicode and 10646 *are* identical. Let me ask something of you Keld,
have you ever read the Unicode standard? If so, then you apparently
have a learning disability; if not, then you have no business making
these statements.

Just to make the facts clear, what Unicode calls an abstract character
*is not* a necessarily a member of the Unicode repertoire. The Unicode
repertoire is precisely the collection of characters coded as single
UCS-2 code values or two UCS-2 code values in the case of surrogate pairs
(i.e., in both instances equivalent to a single UCS-4 code value and
a single element of the 10646 repertoire).
