* Detect passing `$encoding` to `mb_strrpos()` as 3rd argument.
*
* The `$encoding` parameter was moved from the third position to the fourth in PHP 5.2.0.
* For backward compatibility, `$encoding` could be specified as the third parameter, but doing
* so is deprecated and will be removed in the future.
*
* Between PHP 5.2 and PHP 7.3, this was a deprecation in documentation only.
* As of PHP 7.4, a deprecation warning will be thrown if an encoding is passed as the 3rd
* argument.
* As of PHP 8, the argument is expected to change to accept an integer only.
*
* PHP version 5.2
* PHP version 7.4
