    Actually, the first supplementary graphic characters were assigned for
    Unicode 3.1. Unicode 3.2 added only BMP characters.

    And Philippe is correct that the mechanism for surrogates (and
    UTF-16) was published long ago. Actually, it was in Unicode 2.0
    (July, 1996). And the ISO/IEC 10646-1 amendment upon which
    UTF-16 was based was also approved and published in 1996.

    Except then it probably would have been known as Windows 2003
    instead of Windows 2000. :-)
