    ∅ EMPTY SET (U+2205)

    The key is to find the one in the “mathematical operators” section, not some accented O character.

        No, not quite correct. The character pasted off the Swedish page was Ø LATIN CAPITAL LETTER O WITH STROKE (U+00D8).

        It looks almost identical to the to the mathematical symbol for an empty set (at least in the font I’m using right now), but it doesn’t mean anything even slightly similar and would be rendered entirely differently by, for example, a screen reader reading the text aloud.
