Here's a real-life example :
NSString *mot1 = @"arc";
NSString *mot2 = @"a";
NSString *mot3 = @"à";
Unless things have changed recently, GCC isn't UTF-8 aware and may be
doing strange things to your text. Try reading your strings in from a file
or from the UI and try again.
I think (mostly) everyone here is missing the point. The accented "a",
also known as U+0030, does not compare before the word "arc" as it should
(especially since it compares equal to a non-accented "a"). The original
poster had a legitimate problem which had nothing to do with file encodings
but that seems to be all everyone is talking about. The question is, is it
a bug that the accented "a" compares after the word "arc" or is it a
misunderstanding?

That's quite possible. Anyway, if it's the case, I will explain a little
more...
My array of strings is created like this :
dict = [[NSArray alloc] initWithArray:[[NSString
stringWithContentsOfFile:fich] componentsSeparatedByString:@"\r"]];
In the process, another array is created with strings taken from that big
array, and then sorted. I tried with a little array (3 element, see top of
the page for code snippet), and I get it wrong. My case is French, and I
think it's not like Swedish (like å). In French, accented letters are seen
as equivalent to their non-accented counterparts, but IF a word is an
homophone except for its accented letter(s), then it comes after. Here's
another example I tried within my app and still don't work :
mur
mûr
muse
This is correct alphabetical order. BUT,
sortUsingSelector:@selector(compare:) gives me this :
mur
muse
mûr
Since "u" is supposed to be like "û", "s" comes after "r", but not in this
case. Same with sortUsingSelector:@selector(localizedCompare:). The computer
thinks as if "à" (or any other accented letter) is a completely different
letter and likely comes after "z". But that's not the case, at least in
French. (Unlike Swedish, for example, where "å" comes after "z"...
