ing characters (with their numeric values shown in octal):
041 ``!'' 042 ``"'' 043 ``#'' 044 ``$'' 045 ``%''
046 ``&'' 047 ``''' 050 ``('' 051 ``)'' 052 ``*''

072 ``:'' 073 ``;'' 074 ``<'' 075 ``='' 076 ``>''
077 ``?'' 100 ``@'' 133 ``['' 134 ``\'' 135 ``]''
136 ``^'' 137 ``_'' 140 ```'' 173 ``{'' 174 ``|''
