Would it be reasonable to add some kind of escaping code for such situations so that it might print like "BG\x01\x01"?

Ilia, please try 2.6.32, that we support non-printable characters.

Some ACPI tables contain non-printable characters in one of the string fields of the the header - Signature, OemId, OemTableId, or CompilerId. Invalid characters are replaced by '?'.
