ERROR 1253 (42000): COLLATION ‘utf8mb4_unicode_ci’ is not valid for CHARACTER SET ‘utf8’

If you come across the following error in MySQL; don’t be a dumb ass like me.

The error was being thrown from the following statement:

The problem is that the character set should be utf8mb4 not utf8. I was under the impression that the collation of utf8mb4 was part of the utf8 character set. Clearly not.

So the correct statement would be:

Note that you’ll need MySQL version >= 5.5 to use the utf8mb4 character set.
