    I haven't got a dictionary to hand, so I'm relying on my memory of the
    Periodic Table in Chinese, but I think that both 951D/9340 (one
    traditional/simplified pair of characters) and 939D/28C4F (another
    unrelated traditional/simplified pair of characters) are used to
    translate technetium. 951D/9340 aren't directly relevant to Benjamin's
    original points, but I mentioned 951D because it also has a Unihan
    definition of "tc" (having just looked, I now see that 9340 has the
    slightly more helpful definition of "technetium").

    Uh ? Looks like it does to me (simplified gold on the left, U+8345 on
    the right).

    Doesn't look as if it is in Unihan, but then the
    traditional/simplified mappings in Unihan are known to be incomplete.
