Question

How can I let the MySQL InnoDB support the new Unicode character set, such as \U0001f3b8.

The char \U0001f3b8 is a GUITAR which is generated by iPhone’s input method.

The problem is that it cannot be saved in MySQL DB.

The column type that saved is VARCHAR, I have been tried to change to TEXT, still not working.

The Exception is :

Warning: Incorrect string value: ‘\xF0\x9F\x8E\xB8’ for column
‘message’ at row 1

BTW : My working environment is python + Django

I assume that new unicode character set means full UTF-8 support. You need to change your table/column collations to one that include utf8mb4 encoding. Good old utf8 in an incomplete implementation that only supports up to three bytes. You need MySQL/5.5 for that.
