Objective C - unicode（乌尔都语）文件副本

Question

我正在尝试订阅移动到垃圾 MacOS 事件并将文件夹复制回来。代码在默认英文字母下工作正常，但是当我使用乌尔都语和乌尔都语数字格式时 copyItemAtPath 在复制时找不到文件夹。

回调：

void fsevents_callback(ConstFSEventStreamRef streamRef,
    void * userData,
    size_t numEvents,
    void * eventPaths,
    const FSEventStreamEventFlags eventFlags[],
    const FSEventStreamEventId eventIds[]) {
    FSEventsListener * eventListener = (__bridge FSEventsListener * ) userData;
    char ** paths = eventPaths;

    for (int i = 0; i < numEvents; i++) {
        NSString * name = [NSString stringWithFormat: @ "%s", paths[i]];
        NSLog(@ "Path: %@ (flag = %d)", name, eventFlags[i]);

        if (eventFlags[i] & kFSEventStreamEventFlagItemRenamed) {
            [eventListener.delegate fileWasRenamed: name];
        } else {
            [eventListener.delegate fileWasTouched: name];
        }
    }
}

听众：

- (void)fileWasRenamed:(NSString *)aPath
{
    NSString *trashPath = [NSSearchPathForDirectoriesInDomains(NSTrashDirectory, NSUserDomainMask, YES) lastObject];
    if (nil != aPath && NSNotFound != [aPath rangeOfString:trashPath].location)
    {
        NSString *trashFilePath = aPath;
        if (nil != self.removedFilePath && NSNotFound != [trashFilePath.lastPathComponent rangeOfString:self.removedFilePath.lastPathComponent.stringByDeletingPathExtension].location)
        {
            NSError *error = nil;
            NSFileManager *fileManager = [NSFileManager defaultManager];
            BOOL isCopied = [fileManager copyItemAtPath:trashFilePath toPath:self.removedFilePath error:&error];
        }
    }
}

当我尝试复制时出现错误：

错误域=NSPOSIXErrorDomain 代码=2 "No such file or directory"

回收站中的文件名：我的文件夹 17.57.44

[NSString stringWithFormat: @ "%s", paths[i]];

显然不是处理 unicode 字符串的有效方法。使用

[NSString stringWithUTF8String:paths[i]];

反而应该有所帮助。
