ios - 如何将字符串转换为utf8编码？

Question

我正在这样阅读我的应用程序目录

NSArray *pathss = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectorys = [pathss objectAtIndex:0];
NSError * error;
NSMutableArray * directoryContents =  [[NSFileManager defaultManager]
                            contentsOfDirectoryAtPath:documentsDirectorys error:&error];

我得到的输出:

"Forms_formatted.pdf",
"fund con u\U0308u\U0308.pdf",
"hackermonthly-issue.pdf",

这些是文件名。我的问题是，我怎么能将这个名称“fund con u\U0308u\U0308.pdf”转换为正确的格式。提前致谢

也许这会有所帮助:

NSString *documentsDirectorys = [pathss objectAtIndex:0];
const char *documentsDirectoryCstring = [documentsDirectorys cStringUsingEncoding:NSASCIIStringEncoding];

编辑:

const char *documentsDirectoryCstring = [documentsDirectorys cStringUsingEncoding:NSUTF8StringEncoding];
