French thread pedals will be marked "D" and "G" for "droite" (right) and "gauche" (left).
French thread pedals are a bit undersized for standard 9/16" - 20 thread cranks.
French-thread (14 x 1.25) cranks can be retapped to standard size, and many existing cranksets marked that way have already had this done.
