Comment:

 (In [21255]) 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.
