       nkf - Network Kanji code conversion Filter v2.0

       nkf [ options ] [ file ]

       Nkf  is  a  yet  another kanji code converter among networks, hosts and
       terminals.  It converts input kanji code to designated kanji code  such
       as 7-bit JIS, MS-kanji (shifted-JIS), utf-8 or EUC.

       One  of  the  most  unique  facicility of nkf is the guess of the input
       kanji code.  It currently  recognizes  7-bit  JIS,  MS-kanji  (shifted-
       JIS),utf-8  and  EUC.  So users needn't the input kanji code specifica-

       By default X0201 kana is converted into X0208  kana.  For  X0201  kana,
       SO/SI, SSO and ESC-(-I methods are supported. For automatic code detec-
       tion, nkf assumes no X0201 kana in MS-Kanji. To  accept  X0201  in  MS-
       Kanji, use -X, -x or -S.

       Options are bellow:

       -j     output 7-bit JIS code.  This is a default.

       -s     output MS-kanji (shifted-JIS) code.

       -e     output EUC (AT&T) code.

       -w     output UTF-8 (Unicode 8bit form).

       -S     Assume  MS-Kanji and X0201 kana input. It also accpet JIS.  AT&T
              EUC is recognized as X0201 kana. Without -x flag, X0201 kana  is
              converted into X0208.

       -J     Assume   JIS  input.  It also accepts Japanese EUC.  This is the
              default. This flag does not excludde MS-Kanji.

       -E     Assume AT&T EUC input. It also accpet JIS.  Same as -J.

       -B     Assume broken JIS-Kanji, which lost ESC.  Usefull when your site
              is  using  old  B-News  Nihongo patch. -B1 allows any char after
              ESC-( or ESC-$. -B2 forces ASCII after NL.

       -W     Assume UTF-8 input.

       -m     MIME ISO-2022-JP/ISO8859-1 decode. (default)  To  see  ISO8859-1
              (Latin-1)  -l  is  necessary. -mN does loose encoding. It allows
              line break in the middle of the basr64 encoding.

       -mB    Decode MIME base64 encoded stream. Remove header or  other  part
              before conversion.

       -mQ    Decode  MIME quoted stream. '_' in quoted is converted to space.

       -m0    No MIME decode.

       -M     MIME encode. Header style. All ASCII code and control characters
              are intact.

       -MB    MIME  encode.   Base64  stream.  Kanji  conversion  is performed
              before encoding, so this cannot be used as  a  picture  encoder.
              perfome quoted encoding.

       -l     Input  and  output  code is ISO8859-1 (Latin-1) and ISO-2022-JP.
              -s, -e and -x are not compatible with this option.

       -fn    Folding on n length in a line. Default 60. -f40-0 forces 0  mar-
              gin folding.

       -X     Allow  X0201 kana in MS-Kanji.  X0201 is converted into X0208 by
              default.  This is default in MSDOS.

       -x     Try to preseve X0208 kana.  Assume X0201 kana in  MS-Kanji.  And
              do  not  convert X0201 kana to X0208.  In JIS output, ESC-(-I is
              used. In EUC output, SSO is used.

       -Z     Convert X0208 alphabet to ASCII. -Z1 converts X0208  kankaku  to
              one ASCII space. -Z2 converts X0208 kankaku to two ASCII spaces.

       -Z3    Replacing "><&" into '&gt;', '&lt;',  '&quot;',  '&amp;'  as  in

       -I     Replacing Non iso-2022-jp char into the strage geta character.

       -b     bufferd output.  This is a default.

       -u     unbufferd output.

       -t     no operations.

       -O     Output  result to file. The first name in arguments becomes out-
              put.  Please be careful. If there are no file arguments, nkf.out
              is  chosen.   -OW  does  rewriting.  Original  listed  files are
              replaced by filtered result.

       -ic    output ESC-$-c as sequence to designate  JIS-kanji  (Default  is

       -oc    output  ESC-(-c as sequence to designate single-byte roman char-
              acters (Default is B.)

       -r     {de/en}crypt ROT13/47

       -v     display Version

       -T     Text mode output (MS-DOS)

       Nkf cannot handle some input that contains mixed  kanji  codes.   Auto-
       matic code detection becomes very weak with -x, -X and -S.  MIME encod-
       ing is very loose.

       Thanks for those people.
