Queries are not correctly encoded in ruby 1.9

[d11wtq]

On models with Binary properties, which #dump the data with force_encoding("BINARY"), the DataObjects adapter doesn't pay attention to the encoding and builds a "UTF-8" encoded string containing non-UTF-8 data. This manifests in an explosion when using the New Relic middleware, which introspects queries.

Actually, not 100% if this is happening during query execution, or during query logging. It explodes when new relic receives the query as a log entry, which means it's already executed in the DB. I'd have thought with MySQL (which we use), DataObjects adapter would be using prepared statements, but I may be wrong. Haven't got a huge amount of time to look into it right now.
