title: Byte array to utf8 string
body: <p>How do I get my byte array to a string that handles the Swedish letters å ä ö?</p>
  
  <p>I do this at the moment:
  NSString *hexString = [NSString stringWithFormat:@"%c", resData[i]];</p>
  
  <p>(resData contains ascii characters)
  But when I use the hexString in my output label I get jibberish for all non English chars.
  How can I make a selected byte to an encode that handles the Swedish characters?</p>
  
  <p>Regards
