title: How to change an NSString's encoding?
body: <p>I have an NSArray of NStrings, I got this from NSLog when printing the array.
  Here is the code I have implemented:</p>
  
  <pre><code>NSMetadataQuery *query = [[NSMetadataQuery alloc] init];
  .....
  NSArray *queryResults = [[query results] copy];
  
  for (NSMetadataItem *item in queryResults)
  {
      id value = [item valueForAttribute: kMDItemAlbum];
      [databaseArray addObject: value];
  }
