Comment:

 I cleared up the problem - it was my own fault and is not related to the
 WP-Core-DB Layer. Sorry for that.

 I also updated a second field with the same query, with a substringed an
 striptagged version of the long string. i used a substr and not mb_substr
 in this case to shorten the string - leading to toxic UTF-8 multibyte
 Characters in the query which then should fail.

 Sorry for using up your time i am happy that there is no bug inside the
 WP-Core.
 Thanks for your time, i really enjoy using your software.
