```

## Discussion

Discussion Specifies canonical composition according to Unicode 3.2 rules, but using the HFS+ decomposition exclusions. You can use ths option when converting HFS file names. You should use this form when you want to obtain a composed form that can be converted to and from the decomposed form specified by kUnicodeHFSPlusDecompVariant. This is the recommended way to request decompositions with HFS+ exclusions, instead of using mappingVersion = kUnicodeUseHFSPlusMapping.
