TYPO3.Flow

I tried to install Typo3 Neos 1.1 Beta 2 including Flow 2.2 and recieved the exception listed below during setup process.
Database version is 5.5.31-1~dotdeb.0-log (MyISAM engine), PHP version is 5.3.28.
I also tried Typo3 Neos 1.0.2 with same result. Database is UTF-8 as required by Neos.

It seems that the primary key is too long for MySQL running on MyISAM engine and UTF-8 encoding. 3 columns x 255 chars x UTF-8 encoding (3 bytes) > 1000 bytes allowed by MySQL with MyISAM engine. Please provide a fix that works under MyISAM with UTF-8.
