# NAME 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 whether put BOM or not. - __-W32[BL][0]__ UTF-32. B or L gives whether Big Endian or Little Endian. 0 gives whether 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__ Hiragana/Katakana conversion - __-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 '>', '<', '"', '&' 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. - 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 - Windows-31J a.k.a. CP932 - UTF-8 same as UTF-8N - UTF-8N UTF-8 without BOM - UTF-8-BOM UTF-8 with BOM - UTF8-MAC (input only) decomposed UTF-8 - UTF-16 same as UTF-16BE - UTF-16BE UTF-16 Big Endian without BOM - UTF-16BE-BOM UTF-16 Big Endian with BOM - UTF-16LE UTF-16 Little Endian without BOM - UTF-16LE-BOM UTF-16 Little Endian with BOM - UTF-32 same as UTF-32BE - UTF-32BE UTF-32 Big Endian without BOM - UTF-32BE-BOM UTF-32 Big Endian with BOM - UTF-32LE UTF-32 Little Endian without BOM - UTF-32LE-BOM UTF-32 Little Endian with BOM - __--fb-{skip, html, xml, perl, java, subchar}__ Specify the way that nkf handles unassigned characters. Without this option, --fb-skip is assumed. - __--prefix=_escape character__target 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 option. - __--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.
