NAME
NKF - Perl extension for Network Kanji FilterSYNOPSIS
use NKF; $output = nkf("-s",$input);
DESCRIPTION
This is a Perl Extension version of nkf (Netowrk Kanji Filter). It converts the last argument and return converted result. Conversion details are specified by flags before the last argument.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 or UTF-16.
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 and UTF-16. 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
- -b -u
- Output is buffered (DEFAULT), Output is unbuffered.
- -j -s -e -w -w16
- Output code is ISO-2022-JP (7bit JIS), Shift_JIS, EUC-JP, UTF-8N, UTF-16BE. Without this option and compile option, ISO-2022-JP is assumed.
- -J -S -E -W -W16
- Input assumption is JIS 7 bit, Shift_JIS, EUC-JP, UTF-8, UTF-16LE.
-
- -J
- Assume JIS input. It also accepts EUC-JP. This is the default. This flag does not exclude Shift_JIS.
- -S
- Assume Shift_JIS and X0201 kana input. It also accepts JIS. EUC-JP is recognized as X0201 kana. Without -x flag, X0201 kana (halfwidth kana) is converted into X0208.
- -E
- Assume EUC-JP input. It also accepts JIS. Same as -J.
-
- -t
- No conversion.
- -i[@B]
- Specify the Esc Seq for JIS X 0208-1978/83. (DEFAULT B)
- -o[BJH]
- Specify the Esc Seq for ASCII/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)
- -l
- ISO8859-1 (Latin-1) support
- -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
- Converts X0208 kankaku to single ASCII space.
- -Z2
- Converts X0208 kankaku to double ASCII spaces.
- -Z3
- Replacing Fullwidth >, <, ", & into '>', '<', '"', '&' as in HTML.
-
- -X -x
- Assume X0201 kana in MS-Kanji. 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, SSO 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 char after ESC-( or ESC-$.
- -B2
- forces 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
- 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.
- -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 system
- --jis --euc --sjis --mime --base64
- convert for 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 name are case insensitive.
-
- ISO-2022-JP
- a.k.a. RFC1468, 7bit JIS, JUNET
- EUC-JP (eucJP-nkf)
- a.k.a. AT&T JIS, Japanese EUC, UJIS
- eucJP-ascii
- eucJP-ms
- CP51932
- Microsoft Version of EUC-JP.
- Shift_JIS
- a.k.a. SJIS, MS-Kanji
- CP932
- a.k.a. Windows-31J
- UTF-8
- same as UTF-8N
- UTF-8N
- UTF-8 without BOM

- UTF-16 Little Endian without BOM
- UTF-16LE-BOM
- UTF-16 Little Endian with BOM
- UTF8-MAC (input only)
-
- --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 convert string which 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 ``&#....;''.
