Ascii maps a path containing a sequence of ASCII characters and/or names of ASCII characters into the corresponding sequence of ASCII character codes. Other path elements are copied across unchanged.
Ascii:<a 'NUL' 'B' 'BEL' foo c 'ESC' 'D'> = 97 0 66 7 foo 99 27 68.
One can envisage similar functions for other character set standards (ISO-11, etc.).
