New Contents: Previously, the presence of the "\f" character in the Desktop Management Interface (DMI) information or any non-ASCII character in the hardware name rendered the system unable to register to both Red Hat Network (RHN) and Red Hat Network Satellite Server. This error has been fixed, and the system registration now works as expected.
