Thank you very much for the information.
You're welcome.
I even didn't think about the normalization. Wow.. it is quite
complicated.
I tried the 4 methods, -precomposedStringWith[Canonical/
Compatibility]Mapping and -decomposedStringWith[Canonical/
Compatibility]Mapping.
The result was that [NSString UTF8String] returns "precomposed"
version
That's not quite accurate. Any given string will be in precomposed
or decomposed form (or it might not be normalized to either form, and
have a mix). Whatever form that string is in, -UTF8String will
maintain it. So, -UTF8String doesn't necessarily return
"precomposed" form, it just so happens that the string you got was
already in precomposed form.
, while the one used in the FCP was "decomposed".
The low-level file-system APIs on Mac OS X use what Apple calls "file-
system representation", which is mostly decomposed (NFD) with some
specific exceptions. So, any time you obtain a file name from the
file-system -- by enumerating a directory or from an NSOpenPanel, for
example -- it's likely to be mostly decomposed. This is true even if
the name originally used to create the file was passed in precomposed
form.
If you want the string in a specific normalization form for some
reason, you need to transform it using the above methods. Don't rely
on "file-system representation" being in any particular form. You
can compare strings without regard for normalization form using one
of the -compare:... methods and _not_ specifying NSLiteralSearch.
Note that isEqual: and isEqualToString: _do_ specify NSLiteralSearch
(or the equivalent) and so can report NO for two strings which
display identically.
Cheers,
