Plan 9 - man page for ascii (plan9 section 1)

ASCII(1)			     General Commands Manual				 ASCII(1)

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  inter-
       preted  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.  Char-
       acters  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(6)).	If  given  a  range of hexadecimal numbers, unicode prints a table of the
       specified Unicode characters -- their values and UTF representations.  Otherwise it trans-
       lates 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 avail-
       able in the current font.

       The file /lib/unicode contains a table of characters and descriptions, sorted in hexadeci-
       mal 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
	      See the start of the Greek alphabet's encoding in the Unicode Standard.

FILES
       /lib/unicode
	      table of characters and descriptions.
