nkf - Network Kanji Filter

SYNOPSIS

nkf [-butjnesliohrTVvwWJESZxXFfmMBOcdILg] [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 ISO-2022-JP, Shift_JIS, EUC-JP,
UTF-8, UTF-16 or UTF-32.

One of the most unique faculty of nkf is the guess of the input kanji encodings. It
currently recognizes ISO-2022-JP, Shift_JIS, EUC-JP, UTF-8, UTF-16 and UTF-32. So users
needn't set the input kanji code explicitly.

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

OPTIONS

-J -S -E -W -W16 -W32 -j -s -e -w -w16 -w32
Specify input and output encodings. Upper case is input. cf. --ic and --oc.

-J ISO-2022-JP (JIS code).

-S Shift_JIS and JIS X 0201 kana. EUC-JP is recognized as X0201 kana. Without -x
flag, JIS X 0201 Katakana (a.k.a.halfwidth kana) is converted into JIS X 0208. If
you use Windows, see Windows-31J (CP932).

-E EUC-JP.

-W UTF-8N.

-W16[BL][0]
UTF-16. B or L gives whether Big Endian or Little Endian. 0 gives whther put BOM
or not.

-W32[BL][0]
UTF-32. B or L gives whether Big Endian or Little Endian. 0 gives whther put BOM
or not.

-b -u
Output is buffered (DEFAULT), Output is unbuffered.

-t No conversion.

-i[@B]
Specify the escape sequence for JIS X 0208.

-i@ Use ESC ( @. (JIS X 0208-1978)

-iB Use ESC ( B. (JIS X 0208-1983/1990 DEFAULT)

-o[BJ]
Specify the escape sequence for US-ASCII/JIS X 0201 Roman. (DEFAULT B)

-r {de/en}crypt ROT13/47

-h[123] --hiragana --katakana --katakana-hiragana
-h1 --hiragana
Katakana to Hiragana conversion.

-h2 --katakana
Hiragana to Katakana conversion.

-h3 --katakana-hiragana
Katakana to Hiragana and Hiragana to Katakana conversion.

-T Text mode output (MS-DOS)

-f[m [- n]]
Folding on m length with n margin in a line. Without this option, fold length is 60
and fold margin is 10.

-F New line preserving line folding.

-Z[0-3]
Convert X0208 alphabet (Fullwidth Alphabets) to ASCII.

-Z -Z0
Convert X0208 alphabet to ASCII.

-Z1 Convert X0208 kankaku to single ASCII space.

-Z2 Convert X0208 kankaku to double ASCII spaces.

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

-X -x
With -X or without this option, X0201 is converted into X0208 Kana. With -x, try to
preserve X0208 kana and do not convert X0201 kana to X0208. In JIS output, ESC-(-I is
used. In EUC output, SS2 is used.

-B[0-2]
Assume broken JIS-Kanji input, which lost ESC. Useful when your site is using old
B-News Nihongo patch.

-B1 allows any chars after ESC-( or ESC-$.

-B2 force ASCII after NL.

-I Replacing non iso-2022-jp char into a geta character (substitute character in
Japanese).

-m[BQN0]
MIME ISO-2022-JP/ISO8859-1 decode. (DEFAULT) To see ISO8859-1 (Latin-1) -l is
necessary.

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

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

-mN Non-strict decoding. It allows line break in the middle of the base64 encoding.

-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.

-MQ Perform 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.

-L[uwm] -d -c
Convert line breaks.

-Lu -d
unix (LF)

-Lw -c
windows (CRLF)

-Lm mac (CR)

Without this option, nkf doesn't convert line breaks.

--fj --unix --mac --msdos --windows
Convert for these systems.

--jis --euc --sjis --mime --base64
Convert to named code.

--jis-input --euc-input --sjis-input --mime-input --base64-input
Assume input system

--ic=input codeset --oc=output codeset
Set the input or output codeset. NKF supports following codesets and those codeset
names are case insensitive.

--fb-{skip, html, xml, perl, java, subchar}
Specify the way that nkf handles unassigned characters. Without this option,
--fb-skip is assumed.

--prefix=escape charactertarget character..
When nkf converts to Shift_JIS, nkf adds a specified escape character to specified 2nd
byte of Shift_JIS characters. 1st byte of argument is the escape character and
following bytes are target characters.

--no-cp932ext
Handle the characters extended in CP932 as unassigned characters.

--no-best-fit-chars
When Unicode to Encoded byte conversion, don't convert characters which is not round
trip safe. When Unicode to Unicode conversion, with this and -x option, nkf can be
used as UTF converter. (In other words, without this and -x option, nkf doesn't save
some characters)

When nkf converts strings that related to path, you should use this opion.

--cap-input
Decode hex encoded characters.

--url-input
Unescape percent escaped characters.

--numchar-input
Decode character reference, such as "&#....;".

--in-place[=SUFFIX] --overwrite[=SUFFIX]
Overwrite original listed files by filtered result.

Note --overwrite preserves timestamps of original files.

--guess=[12]
Print guessed encoding and newline. (2 is default, 1 is only encoding)

--help
Print nkf's help.

--version
Print nkf's version.

-- Ignore rest of -option.
