Recording Cyrillic in the database?

Question

PHP

There is a problem with writing Cyrillic characters to the database...
For some reason, an empty string is written or nothing is written at all...
File encoding - UTF-8 without bom
Table encoding - utf_8_general_ci
Connection encoding - UTF-8 ( $this->DBH->exec ('SET NAMES utf8'); )
But still nothing is written, what could be the reason?

Answer 1

Throw the code with which you write to the database and what engine is used there (MyISAM / InnoDB etc ...).
By the way, "$this->DBH->exec('SET NAMES utf8');" this does not expose the connection encoding..)
