    No one from the official Unicode.org company replied to me last time,
    so I'll try again.

    Why is it that the entry for Kelvin (a measurement of temperature),
    has a decomposition, which is listed as a canonical decomposition, to
    the standard ASCII "K"?

    This decomposition is actually a compatibility decomposition.

    How does this cause me problems? I've written a parser for
    UnicodeData.txt. This parser will extract data for decomposition, and
    for composition also.

    Because Kelvin canonically decomposes to K, it follows that K
    cannonically composes to Kelvin! :o(

    So my composer will change a word like this: "Kitchen", into "(Kelvin)
    itchen". Which is just totally wrong. All because UnicodeData.txt is
    broken.

    That is what I think. But I might be wrong.

    Can someone from Unicode.org please confirm or deny all of this? That
    will put my mind at rest, because I need the official answer.
