title: Incorrect string value \xF0\x9F\x98\x8A\xF0\x9F... for column 'desc'
body: <p>I'm having this error and still don't know why.</p>
  <p>I predict it's happen because some users try to use an emoji. But I try a lot of emoji and it all work.</p>
  <p>I use Mysql 5.7
  I already set column to COLLATE utf8mb4_unicode_ci and table to CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci</p>
