as your example shows, normalization behavior is in fact not OS
dependent, but rather filesystem specific:
it is the HFS+ volume format that mandates storing filenames in a
specific fixed normalization form (which is not exactly NFD as per
UAX#15, e.g. some hangul chars are not decomposed [1]), other
filesystems on the mac do not have this requirement (e.g. NTFS), and
conversely, HFS+ volumes can be mounted on non-mac systems (e.g.
linux [2]) and expose its specific normalization behavior there...
