Log:

check for charset conversion errors before DB update 1215. Fixes #5070

the database charset handling was fragile before the change to UTF-8.
We abused latin1 as tranparent byte storage of UTF-8 string. If for example
the default connection charset was set to something else than latin1
charset conversions in the mysql server would have stored data, our charset
updates 1215 and 1216 will destroy data sometimes resulting in duplicate keys.
This patch checks if the conversions succeed in temporary tables before doing
the real update.
