    Indeed. The last two, BTW, are because the ASCII repertoire has taken
    on a life of its own: ^ is not merely a spacing clone of COMBINING
    CIRCUMFLEX, but has become a fully distinct character with many functions.
    In particular, none of the Unicode canonical forms will affect text
    written solely in the ASCII repertoire. "Every character has its
    own story."

    Someone asked about whether XML documents SHOULD or MUST be in NFC.
    The answer is SHOULD, and this is formally applied only to the
    not-yet-promulgated XML 1.1. XML documents *on the Web* SHOULD be in
    NFC by reason of the W3C Character Model.
