If a char* is destined for the file system, you should be using
-fileSystemRepresentation, not -UTF8String.
I forget that all the time.
To be honest I rarely remember to call -fileSystemRepresentation.
The docs seem to indicate that its only purpose is to replace
abstract / and . characters with OS equivalents.
On OS X this would have seem to have no net result.
Is there more to this?
For some codepoints (e.g. umlauts) there is more than one way to
represent them in Unicode (composed/decomposed):
NSString *str = @"/äöü.txt";
const char *utf8 = [str UTF8String];
const char *file = [str fileSystemRepresentation];
NSLog(@"utf8: %zd %s", strlen(utf8), utf8);
NSLog(@"file: %zd %s", strlen(file), file);
Results (depending on the filesystem, I guess) in:
UTFFilename[6260:403] utf8: 11 /<glyphs>.txt
UTFFilename[6260:403] file: 14 /<different glyphs>.txt
Think of it as "umlaut-a/o/u" vs. "a/o/u, as umlaut"
Both encodings work but e.g. SVN has (had) problems with files that
contain umlauts: They used the composed name internally but the
filesystem returns the decomposed variant on OS X. Blindly comparing the
UTF-8 byte arrays failed.
Bye,
Daniel
