       Ascii  prints  the  ASCII  values  corresponding to characters and vice
       versa;  under  the  -8  option,	the  ISO  Latin-1  extensions	(codes
       0200-0377)  are	included.   The	 values	 are interpreted in a settable
       numeric base; -o specifies  octal,  -d  decimal,	 -x  hexadecimal  (the
       default), and -bn base n.

       With  no	 arguments,  ascii  prints a table of the character set in the
       specified base.	Characters of text are converted to their  ASCII  val‐
       ues, one per line. If, however, the first text argument is a valid num‐
       ber in the specified base, conversion goes the opposite	way.   Control
       characters  are	printed	 as  two- or three-character mnemonics.	 Other
       options are:

       -n     Force numeric output.

       -c     Force character output.

       -t     Convert from numbers to running text; do not  interpret  control
	      characters or insert newlines.

       Unicode	is  similar; it converts between UTF and character values from
       the Unicode Standard (see utf(6)).  If given  a	range  of  hexadecimal
       numbers,	 unicode  prints a table of the specified Unicode characters —
       their values and UTF representations.  Otherwise it translates from UTF
       to numeric value or vice versa, depending on the appearance of the sup‐
       plied text; the -n option forces numeric output to avoid ambiguity with
       numeric	characters.  If converting to UTF , the characters are printed
       one per line unless the -t flag is set, in which case the output	 is  a
       single  string containing only the specified characters.	 Unlike ascii,
       unicode treats no characters specially.

       The output of ascii and unicode may  be	unhelpful  if  the  characters
       printed are not available in the current font.

       The  file /lib/unicode contains a table of characters and descriptions,
       sorted in hexadecimal order, suitable for look(1) on the lower case hex
       values of characters.

       ascii -d
	      Print the ASCII table base 10.

       unicode p
	      Print the hex value of `p'.

       unicode 2200-22f1
	      Print a table of miscellaneous mathematical symbols.

       look 00039 /lib/unicode
	      See  the	start  of the Greek alphabet's encoding in the Unicode

	      table of characters and descriptions.
