VMS Help DSR, DSR Commands, .ENABLE OVERSTRIKING  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The .ENABLE OVERSTRIKING and .DISABLE OVERSTRIKING commands
    enable and disable the overstrike function.

    You use the Overstrike flag (%) to create special characters that
    are not available on the terminal by overstriking any printing
    character with another. For example, you can overstrike a 7 with
    a hyphen to create a European 7.

    Operation of the overstrike function is initially enabled
    (.ENABLE OVERSTRIKING), but recognition of the Overstrike flag
    (%) is not turned on (.NO FLAGS OVERSTRIKE).
