I find that I am in need of dealing with versions of strings that may be
turned into file names, and thus I need to be comparing normalised
forms. However, according to
https://developer.apple.com/library/content/qa/qa1173/_index.html, "For
example, HFS Plus (Mac OS Extended) uses a variant of Normal Form D in
which U+2000 through U+2FFF, U+F900 through U+FAFF, and U+2F800 through
U+2FAFF are not decomposed (this avoids problems with round trip
conversions from old Mac text encodings)."
Is there a way to get at this variant? [NSString
decomposedStringWithCanonicalMapping] returns "A string made by
normalizing the string’s contents using the Unicode Normalization Form
D." That seems not to give what I need, but I haven't seen a better
option. Is there such a method?
