Comment 2 for bug 1485195

No, this is a different issue (although similar in spirit). lower_boundary and upper_boundary can be a blob, and that doesn't affect me. The problem is the table and db name get filled with the null character because they get transformed into blobs. db nad tbl should always be utf8, as they are going to be utf8 if mysql >= 5.5.

I did a pull request on https://github.com/percona/percona-toolkit/pull/48 I think you may want to solve it differently, but that is what works for me.
