-     * Use an ‘M’ to represent meta characters (characters with the 8th bit set),

-     *
-     *      \040    Represents ASCII space.
-     *
-     *      \240    Represents Meta-space (&nbsp in HTML).

-     *
-     *      \M^C    Represents control character ‘C’ with the 8th bit set.
-     *              Spans characters ‘\200’ through ‘\237’, and ‘\377’ (as ‘\M^?’).

-     *      \^C     Represents the control character ‘C’.
-     *              Spans characters ‘\000’ through ‘\037’, and ‘\177’ (as ‘\^?’).
