Issue

<U+2216, U+FE00> looks different from U+2216, but that sequence is not a standardized variation sequence. U+FE00 should have no effect in that context.

I don't know where this UVS idea came from but it obviously came from somewhere, so I've disabled it for now (and removed the glyphs from exporting to the final TTF) rather than deleting it from the font sources. The ccmp substitutions contained this:

sub setminus VS1 by setminus.uv001;
sub setminus VS1 by setminus.uv001.ssty1;
sub setminus VS1 by setminus.uv001.ssty2;

which is clearly wrong.
