NAME

       tcs - translate character sets

SYNOPSIS

       tcs [ -slcv ] [ -f ics ] [ -t ocs ] [ file ...  ]

DESCRIPTION

       Tcs  interprets the named file(s) (standard input default) as a stream of characters from the ics character set or format, converts them to
       runes, and then converts them into a stream of characters from the ocs character set or format on the standard output.  The  default  value
       for  ics  and ocs is utf, the UTF encoding described in utf(6).	The -l option lists the character sets known to tcs.  Processing continues
       in the face of conversion errors (the -s option prevents reporting of these errors).  The -c option forces the output to contain only  cor-
       rectly  converted characters; otherwise, 0x80 characters will be substituted for UTF encoding errors and 0xFFFD characters will substituted
       for unknown characters.

       The -v option generates various diagnostic and summary information on standard error, or makes the -l output more verbose.

       Tcs recognizes an ever changing list of character sets.	In particular, it supports a variety of Russian and Japanese encodings.   Some	of
       the supported encodings are

       utf    The Plan 9 UTF encoding, known by ISO as UTF-8

       utf1   The deprecated original UTF encoding from ISO 10646

       ascii  7-bit ASCII

       8859-1 Latin-1 (Central European)

       8859-2 Latin-2 (Czech .. Slovak)

       8859-3 Latin-3 (Dutch .. Turkish)

       8859-4 Latin-4 (Scandinavian)

       8859-5 Part 5 (Cyrillic)

       8859-6 Part 6 (Arabic)

       8859-7 Part 7 (Greek)

       8859-8 Part 8 (Hebrew)

       8859-9 Latin-5 (Finnish .. Portuguese)

       koi8   KOI-8 (GOST 19769-74)

       jis-kanji
	      ISO 2022-JP

       ujis   EUC-JX: JIS 0208

       ms-kanji
	      Microsoft, or Shift-JIS

       jis    (from only) guesses between ISO 2022-JP, EUC or Shift-Jis

       gb     Chinese national standard (GB2312-80)

       big5   Big 5 (HKU version)

       unicode
	      Unicode Standard 1.0

       tis    Thai character set plus ASCII (TIS 620-1986)

       msdos  IBM PC: CP 437

       atari  Atari-ST character set

EXAMPLES

       tcs -f 8859-1
	      Convert 8859-1 (Latin-1) characters into UTF format.

       tcs -s -f jis
	      Convert characters encoded in one of several shift JIS encodings into UTF format.  Unknown Kanji will be converted into 0xFFFD char-
	      acters.

       tcs -lv
	      Print an up to date list of the supported character sets.

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 val-
       ues, 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 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 ambigu-
       ity 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
	      See the start of the Greek alphabet's encoding in the Unicode Standard.

FILES

       /lib/unicode
	      table of characters and descriptions.
