How to fix encoding to UTF8 in iOS?

Question

iOS

I get id3 tag from mp3 in iOS application from a song with a Russian name.
I use:

AVMetadataItem *item = [self.player.metaData objectAtIndex:0];
self.nameSong.text = item.stringValue;
NSLog("%@");

I get:
ÐÐРЯЧÐÐ+ШÐÐÐÐÐÐ+СТÐÐЫ+//+СÐУШÐЮТ:+1655
There are no problems with English.
How to solve the problem with Russian titles?

Answer 1

Maybe not relevant anymore, but I found a solution, I hope someone will find it useful
const char *charValue = [item.stringValue cStringUsingEncoding:NSISOLatin1StringEncoding];
NSString *returnStr = [[NSString alloc]initWithCString:charValue encoding:NSUTF8StringEncoding];
