    I am truly surprised that UTC would even attempt such a list. I can't
    imagine where one would draw a line such that these two characters here
    are similar enough to be considered spoof buddies, and those two over
    there are not.

    It is *at least* as slippery a slope as definitively mapping traditional
    Chinese to simplified and vice versa (which is more than the existing
    kSimplifiedVariant and kTraditionalVariant fields attempt to do).

    Good luck.
