One potential complication: AIUI the Arel-Ezgi-Uzdilek system for notating Turkish music, which divides each whole tone into nine koma, uses both, along with a few altered sharps.

Some of the Turkish systems are discussed by Ozan Yarman, "A Comparative Evaluation of Pitch Notations in Turkish Makam Music”.
