Doesn't support text with four byte UTF-8 symbols
If you try and submit a review with a 4 byte UTF-8 character in the summary or description you get an error like this:
Incorrect string value: '\xF0\x9F\x98\x80' for column 'summary' at row 1
It turns out that MySQL only supports 3 byte UTF-8 characters with the 'utf8' character type - you need to use 'utf8mb4' to include 4-byte characters.
Please switch ODRS to using this!
