MySQL’s utf8
permits only the Unicode characters that can be represented with 3 bytes in UTF-8. Here you have a character that needs 4 bytes: \xF0\x90\x8D\x83 (U+10343 GOTHIC LETTER SAUIL).
If you have MySQL 5.5 or later you can change the column encoding from utf8
to utf8mb4
. This encoding allows storage of characters that occupy 4 bytes in UTF-8.
You may also have to set the server property character_set_server
to utf8mb4
in the MySQL configuration file. It seems that Connector/J defaults to 3-byte Unicode otherwise:
For example, to use 4-byte UTF-8 character sets with Connector/J, configure the MySQL server with
character_set_server=utf8mb4
, and leavecharacterEncoding
out of the Connector/J connection string. Connector/J will then autodetect the UTF-8 setting.
