NAME
nkf - Network Kanji code conversion Filter v2.0
SYNOPSIS
nkf [ options ] [ file ]
DESCRIPTION
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-
tion.
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-$. -B2 forces ASCII after NL.
-W Assume UTF-8 input.
-m MIME ISO-2022-JP/ISO8859-1 decode. (default) To see ISO8859-1
(Latin-1) -l is necessary. -mN does loose encoding. It allows
line break in the middle of the basr64 encoding.
-mB Decode MIME base64 encoded stream. Remove header or other part
before conversion.
-mQ Decode MIME quoted stream. '_' in quoted is converted to space.
-m0 No MIME decode.
-M MIME encode. Header style. All ASCII code and control characters
are intact.
-MB MIME encode. Base64 stream. Kanji conversion is performed
before encoding, so this cannot be used as a picture encoder.
perfome quoted encoding.
-l Input and output code is ISO8859-1 (Latin-1) and ISO-2022-JP.
-s, -e and -x are not compatible with this option.
-fn Folding on n length in a line. Default 60. -f40-0 forces 0 mar-
gin folding.
-X Allow X0201 kana in MS-Kanji. X0201 is converted into X0208 by
default. This is default in MSDOS.
-x Try to preseve X0208 kana. Assume X0201 kana in MS-Kanji. And
do not convert X0201 kana to X0208. In JIS output, ESC-(-I is
used. In EUC output, SSO is used.
-Z Convert X0208 alphabet to ASCII. -Z1 converts X0208 kankaku to
one ASCII space. -Z2 converts X0208 kankaku to two ASCII spaces.
-Z3 Replacing "><&" into '>', '<', '"', '&' as in
HTML.
-I Replacing Non iso-2022-jp char into the strage geta character.
-b bufferd output. This is a default.
-u unbufferd output.
-t no operations.
-O Output result to file. The first name in arguments becomes out-
put. Please be careful. If there are no file arguments, nkf.out
is chosen. -OW does rewriting. Original listed files are
replaced by filtered result.
-ic output ESC-$-c as sequence to designate JIS-kanji (Default is
B.)
-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)
-c add CR after NL.
-d delete CR after NL.
-L[wmu] new line mode
-Lu unix (LF)
-Lw windows (CRLF)
-Lm mac (CR)
default no conversion
-F
New line preserving line folding.

BUGS
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.
ACKNOWLEDGE
Thanks for those people.
