As discussed in bug 11944 we should use utf8_mb4 as default mysql encoding where the mysql version allows for it. This would allow for the entire utf8 character range rather than an arbitrarily truncated set as chosen by mysql during their first attempt at utf8 compatibility.
As promised, I've opened this followup bug to track this issue.

Back.. Of course it doesn't.. They came in from the clone bug. Oops
Martin, do u plan to provide a patch for this one?
