From my experience, I think thats correct. Whatever case you create something as
is the actual case that it is stored as. But, the ability to open a file is
'case insensitive'. Therefore, while it does preserve case when creating a file,
you cannot have two files with the same 'case insensitive' name, but having
different cases in the name. I just proved this by duplicating a file in the
Finder, removing the ' copy' suffix and trying to changing the case of one
character. The Finder told me that name already exists, which it does in 'case-
insensitive' land.
Or to put it another way... the File System searches for files in a case-
insensitive manor. That search is used both for opening files and for checking
for duplicates when creating a new file.
Also keep in mind that everything I have said here is true for file-names stored
in the 'Roman' script system (which encompances all of the romance languages).
When you get into multi-byte script systens (e.g. Kanji, et al, [which the MacOS
does support]), then the rules of that script system might be different.
