Cute, I never thought of that! However it does't quite work because the
*approximate* 20C fat
is independent of the koron (which is *approximately* 40C). So the equation
'>' = "#p' is an exact constraint.
Anyways the 20C flat note is not considered an accidental, not notated,
inconsistently used, and
irrelevant for notation.

If you look at the persian.ly file I sent, you will find the symbol for that I
think (a blank).
