The relevant text before was,

"I'm talking about looking for a U+2654 glyph for ordinary text when
all the first font tried has is:

 2654 FE01; Chesspiece on white; # WHITE CHESS KING
 2654 FE02; Chesspiece on black; # WHITE CHESS KING"

What my conceptual example font has is not the sort of glyph one would
want for sentences like "Alice ♙ d4 meets White Queen ♕ (with shawl)".

I'm trying to work out whether we need a variation sequence for
"chesspiece in a sentence".  We need the advice of someone who's worked
on font fallback.

You don't need substitution tables to be executed if your application
can just look up glyphs for variation sequences.
