/**
* Issue 411
*
* InnoDB has a maximum index length of 767 bytes, so with utf8mb4
* you can only store 191 characters. This means that when you
* subsequently add an index to the column you get a
* (not-so-obvious) MySQL-error. That's why we limit the varchar to
* 191 chars and then switch to TEXT type.
*
* @file RedUNIT/Mysql/Issue411.php
* @desc Tests intermediate varchar 191 type for MySQL utf8mb4.
