Right, but also from the PGN-standard:
"8.2.3.7: Import and export SAN
PGN export format always uses the above canonical SAN to represent moves in the
movetext section of a PGN game. Import format is somewhat more relaxed and it
makes allowances for moves that do not conform exactly to the canonical format.
However, these allowances may differ among different PGN reader programs. Only
data appearing in export format is in all cases guaranteed to be importable
into all PGN readers."
So a idea is to let your program read moves like Rcf2 but always output the
correct Rf2
