I don't know to what extent this affects HFS+, but case insensitivity in general is locale dependent. The classic example is the Turkish distinction between dotted and dotless I - http://en.m.wikipedia.org/wiki/Dotted_and_dotless_I http://en.m.wikipedia.org/wiki/Dotted_and_dotless_I. Quote: The dotless I, I ı, denotes the close back unrounded vowel sound (/ɯ/). Neither the upper nor the lower case version has a dot. The dotted I, İ i, denotes the close front unrounded vowel sound (/i/). Both the upper and lower case versions have a dot. End quote. I can imagine that being a nightmare, particularly if one user uses a Turkish locale and another on the same machine uses English. And all of that complexity in the kernel? Ouch. (Or HFS+ just behaves incorrectly for Turkish file names, not sure that's really better?)
