java.sql.SQLException: Incorrect string value: '\xF3\xBE\x8D\x81'_问答_开发者

I am getting the following exception while trying to save some Tweets,

You must add a character set and a collation to column twtText. So your column should look like this:

twtText varchar(800) character set utf8 collate utf8_polish_ci DEFAULT NULL,

Change utf8_polish_ci with what collation you want.

Run the following query to see the available collations:

SHOW COLLATION;

MySQL 5.0/5.1 does not support 4byte UTF8-characters, this is a known limitation. MySQL 5.5 does support 4byte UTF8-characters.

See 9.1.10. Unicode Support

It looks like a valid utf-8 sequence, that encodes the following character U+FE341.

As you can see, this is a Unicode character that uses more than 2 bytes. From this and this I deduce that MySQL still doesn't support this subset of Unicode characters (at least for versions < 5.5).
