Re: Proposal to add standardized variation sequences for chess notation

2654 FE00; Chesspiece on white; # WHITE CHESS KING

Why do the ones with white background need a variation selector?

25A1 FE00; White chessboard square; # WHITE SQUARE
25A8 FE01; Black chessboard square; # SQUARE WITH UPPER RIGHT TO LOWER LEFT

I see that you want a fallback in case the variation selectors aren't
supported; but isn't the convention that one "always" start with FE00
for each character that may have variation selectors applied?

So in this case, one would only need variation selector FE00; if applied
to 25A1 or 25A8 giving the chess board variety, if applied to a chess piece
character, gives "checkered" ("black") background (without, one gets the
white background).

Why not use 25A0 BLACK SQUARE with the variation selector? (I know that
it would not entirely black with the variation selector (if not fallback).)
I mean, there is no absolute LOGICAL NEED to draw the "black" background
as WITH UPPER RIGHT TO LOWER LEFT FILL, it could go the other direction
or be just "gray" (or for that matter medium blue...); font maker choice.

Kind regards
