I've written a program to do find and replace on a list of filenames.
It works quite well, but testing revealed problems with accented
characters such as i in a filename. I've come up with a workaround,
but I don't understand why it's necessary, and am curious if I'm
missing something.
I run an NSOpenPanel, allow multiple file selection, get the selected
file list as an NSArray, and send it to this method:
- (void)buildPathsArrayWithArray:(NSArray *)array{
NSEnumerator *e = [array objectEnumerator];
NSMutableDictionary *dict = [NSMutableDictionary
dictionaryWithCapacity:2];
NSString *oldPath = nil;
NSString *encodedPath = nil;
NSData *data;
while(oldPath = [e nextObject]){
data = [oldPath dataUsingEncoding:NSMacOSRomanStringEncoding];
encodedPath = [[[NSString alloc] initWith
Data:data
encoding:NSMacOSRomanStringEncoding] autorelease];
// NSLog(@"encodedPath is %@", encodedPath);
[dict setObject:encodedPath forKey:@"Old Path"];
[dict setObject:@"" forKey:@"New Path"];
... do more stuff...
[pathsArray addObject:[dict copy]];
[dict removeAllObjects];
}
}
Unless I use NSMacOSRomanStringEncoding, things don't work right (I'm
using the AGRegex framework for find/replace). I originally used the
oldPath variable directly, and for a filename of "iagSGAMMA" (randomly
chosen), my [pathsArray description] gave
"e\U0301a\U0301c\U0327SGAMMA". After my NSMacOSRomanStringEncoding
stuff, the array has "\U00e9\U00e1\U00e7SGAMMA" which actually works.
Has anyone else run across this, or know of a better way to handle it?
thanks,
Adam Maxwell
