Summary0004488: UPDATE triggers have local variables defined with hardcoded "utf8" charset
DescriptionHi,

There is hardcoded "utf8" charset in MySql Trigger Template in definition of local variables "var_row_data" and "var_old_data" here:
https://github.com/JumpMind/symmetric-ds/blob/3.12/symmetric-client/src/main/java/org/jumpmind/symmetric/db/mysql/MySqlTriggerTemplate.java#L90

Other "SYM_" triggers (AFTER INSERT, AFTER DELETE) are not affected.

This causes error when the database and its tables support "utf8mb4" charset and you try to update row with some unicode character (ie. adding an emoji to some varchar cell of a row). MySQL fails with error:

"Incorrect string value: '\xF0\x9F\x98\x81V\xC3...' for column 'var_row_data' at row 1"

preventing the row to be updated.

Please remove hardcoded charset definition or add a possibility to set desired charset in some configuration.

Thanks.

We'll use utf8mb4 for MySQL 5.5.3 and newer, but continue to use utf8 for older versions, if the user doesn't specify one. The user can specify character set by setting db.master.collation parameter.
