Hmmmm. It should be "malformed string", actually.

And passing non-ASCII strings inside SQL statements?

This is expected. With NONE, the engine has no idea what charset has the 
SQL text passed from the client. But it has to write it into the UNICODE 
column MON$SQL_TEXT. During copying, the value is verified to be 
well-formed from the destination charset point of view, thus the error 
is thrown.
