You can read "unknown" as "string literal for which the query does not
provide sufficient context to assign a definite type".  I dunno what the
OLE driver really needs to do with the datatype info, but I suppose that
treating this as equivalent to "text" is not unreasonable.  Ask the
complainant what *he* thinks it should do.
