  <p>I changed utf8mb4 from utf8 for iOS5's emoji. They are represented by 4byte code.</p>
  
  <p>But when I inserted 3 smiley emojis, '???' is in mysql.</p>
  
  <p>They are 3F 3F 3F (Hex).</p>
  
  <p>I can store iOS4's emojis well, but not iOS5's.</p>
  
  <p>How could I store iOS5's emojis? </p>
  
  <p>Please help me.</p>
