Comment (by Fahrain):

 tested it with 4.1.2 and 4.1.3. As i can see - 4.2 uses the same code in
 this function.
 I'm planning to upgrade to 4.2 at the next few days, need to do some
 tests.

 I think the problem is in incorrect encoding detection so when i disable
 'utf8' in this 'if' all input data will be send to database to test it:

 {{{
 ...
 // We couldn't use any local conversions, send it to the DB.
 $value['db'] = $db_check_string = true;
 ...
 }}}

 where this encoding detection works right or just didn't changes input
 data
