File name encoding problem

Hi all,

I have a problem figuring out how to match file names returned from
NSFileManger with file names found in a UTF8 encoded XML file.
NSFileManger returns something different from UTF8, but so far I have not
been successful to match the encodings.
I have set my editor in XCode to UTF8 encoding, so the display looks ok.

Here is the dource code, with a few things I tried:

#import <Foundation/Foundation.h>

int main (int argc, const char * argv[]) {
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
    int test1 = 0, test2 = 0;

    NSFileManager* fmgr = [NSFileManager defaultManager];
    NSMutableSet* settingsToRemove = [NSMutableSet setWithObjects:
        [NSString stringWithUTF8String:"High Quality.joboptions"],
        [NSString stringWithUTF8String:"Press Quality.joboptions"],
        [NSString stringWithUTF8String:"Smallest File Size.joboptions"],
        [NSString stringWithUTF8String:"Standard.joboptions"],
        [NSString stringWithUTF8String:"Qualitˆ© presse.joboptions"],
        [NSString stringWithUTF8String:"Qualitˆ© standard.joboptions"],
        [NSString stringWithUTF8String:"Qualitˆ© supˆ©rieure.joboptions"],
        [NSString stringWithUTF8String:"Taille de fichier
minimale.joboptions"],
        nil];
    NSLog(@"objects: %d",[settingsToRemove count]);
    NSEnumerator *enumerator1 =  [settingsToRemove objectEnumerator];
    NSString* inSet;
    while (inSet = [enumerator1 nextObject]) {
        NSLog(@"inSet: %@", inSet );
        inSet = [inSet decomposedStringWithCanonicalMapping];
        NSLog(@"inSet1: %@", inSet );
        inSet = [fmgr stringWithFileSystemRepresentation:[inSet
fileSystemRepresentation] length:[inSet length]];
        NSLog(@"inSet2: %@", inSet );

    } // end while

    NSString* myPath = @"/Users/Shared/Adobe PDF 6.0/Settings";
    NSArray* files = [fmgr directoryContentsAtPath:myPath];
    NSEnumerator *enumerator =  [files objectEnumerator];
    NSString* fileObj;

    while (fileObj = [enumerator nextObject]) {
        NSLog(@"file: %@", fileObj );
        if ([settingsToRemove containsObject:fileObj])    {
            NSLog(@"found file to remove: %@", fileObj );
                test2++;
        } // end if
    } // end while
    test1 = [settingsToRemove count];
    NSLog(@"found files: %d", test2 );
    [pool release];
    return 0;
}

And here is the output from the run log:

I am probably overlooking something obvious. Please point me into the right
direction.
Thanks in advance
