ascii, unicode - interpret ASCII, Unicode characters

Ascii  prints  the  ASCII values corresponding to characters and viceversa; 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.
