Case Preserving and Case Sensitive are subtly two different things. Most case insensitive file systems are case preserving and whatever the UTF8 equivalent is I forget the name.

But the gps point is that assuming you know the semantic meaning of the case and if retention is enough is silly.

Assuming case insensitivity is bizarre.

heh, I especially enjoy that in a huge thread about how capitalization does and doesn't matter, "gps point" was not, in fact, concerning some coordinates of the global positioning system but rather "GP's point". I first chalked it up to some autocomplete artifact but then realized what was actually happening

Perfect is the enemy of good. It is quite acceptable to streamline the easy cases now and the hard cases later or never.
