NAME

       ascii, unicode - interpret ASCII, Unicode characters

SYNOPSIS

       ascii [ -8 ] [ -oxdbn ] [ -nct ] [ text ]

       unicode [ -nt ] hexmin-hexmax

       unicode [ -t ] hex [ ...  ]

       unicode [ -n ] characters

       look hex /lib/unicode

DESCRIPTION

       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 values, one per line. If, however, the
       first text argument is a valid number 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(7)).  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
       supplied  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.

EXAMPLES

       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 039 /lib/unicode
