.SH NAME
nkf \- Network Kanji code conversion Filter v1.9
.SH SYNOPSIS
.B nkf
[
.B options
] [
.B file
]
.SH DESCRIPTION
.PP
.B 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) or EUC.
.PP
One of the most unique facicility of 
.B nkf
is the guess of the input kanji code.
It currently recognizes 7-bit JIS, MS-kanji (shifted-JIS) and EUC.
So users needn't the input kanji code specification.

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 MS-Kanji. To accept X0201 in MS-Kanji, use \-X, \-x or
\-S.
.PP
Options are bellow:
.TP
.B \-b
bufferd output.
This is a default.
.TP
.B \-u
unbufferd output.
.TP
.B \-t
no operations.
.TP
.B \-j
output 7-bit JIS code.
This is a default.
.TP
.B \-s
output MS-kanji (shifted-JIS) code.
.TP
.B \-e
output EUC (AT&T) code.
.TP
.BI \-i c
output 
.BI ESC\-$\- c
as sequence to designate JIS-kanji
(Default is

.B \-MB
MIME encode.  Base64 stream. Kanji conversion is performed before encoding,
so this cannot be used as a picture encoder.
.TP
.B \-l
Input and output code is ISO8859-1 (Latin-1) and ISO-2022-JP.
\-s, \-e and \-x are not compatible with this option.
.TP
.BI \-f n
Folding on 
.BI n 
length in a line. Default 60.
.TP
.B \-X
Allow X0201 kana in MS-Kanji.  
X0201 is converted into X0208 by default.
This is default in MSDOS.
.TP
.B \-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.
.TP
.B \-Z
Convert X0208 alphabet to ASCII. \-Z1 converts X0208 kankaku to one 
ASCII space. \-Z2 converts X0208 kankaku to two ASCII spaces.
.TP
.B \-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.
.TP
.B \-J
Assume  JIS input. It also accepts Japanese EUC.
This is the default. This flag does not excludde MS-Kanji.
.TP
.B \-E
Assume AT&T EUC input. It also accpet JIS.
Same as \-J.
.TP
.B \-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.
.TP
.B \-O
Output result to file. The first name in arguments becomes output.
Please be careful. If there are no file arguments, nkf.out is chosen.
.TP
.B \-c
add CR after NL.
.TP
.B \-d
delete CR after NL.

Automatic code detection

=head1 NAME

NKF - Perl extension for Network Kanji Filter 

=head1 SYNOPSIS

  use NKF;
  $output = nkf("-s",$input);

=head1 DESCRIPTION

This is a Perl Extension version of nkf (Netowrk Kanji Filter ) 1.7.
It converts the last argument and return converted result. Conversion
details are specified by flags before the last argument.

Flags:

C<b,u      Output is bufferred (DEFAULT),Output is unbufferred>

C<j,s,e    Outout code is JIS 7 bit (DEFAULT), Shift JIS, AT&T JIS (EUC)>

C<J,S,E    Input assumption is JIS 7 bit , Shift JIS, AT&T JIS (EUC)>

C<t        no conversion>

C<i_       Output sequence to designate JIS-kanji (DEFAULT B)>

C<o_       Output sequence to designate ASCII (DEFAULT B)>

C<r        {de/en}crypt ROT13/47>

C<m[BQ]    MIME decode [B:base64 stream,Q:quoted stream]>

C<l        ISO8859-1 (Latin-1) support>

C<f        Folding: C<-f60> or C<-f>>

C<Z[0-2]   Convert X0208 alphabet to ASCII  1: Kankaku to space,2: 2 spaces>

C<X,x      Assume X0201 kana in MS-Kanji, C<-x> preserves X0201>

C<B[0-2]   Broken input  0: missing ESC,1: any X on ESC-[($]-X,2: ASCII on NL>

C<d,c      Delete \r in line feed, Add \r in line feed>


C<m0 No MIME decode.>

C<M MIME encode. Header style. All ASCII code and control characters are intact.>

C<MB MIME encode.  Base64 stream. Kanji conversion is performed before encoding, so this cannot be used as a picture encoder.>

C<l Input and output code is ISO8859-1 (Latin-1) and ISO-2022-JP.>

C<L[wmu] new line mode>

C<    -Lu   unix (LF) >

C<    -Lw   windows (CRLF) >

C<    -Lm   mac (CR) >

C< --fj,--unix,--mac,--msdos, --windows convert for these system>

C< --jis,--euc,--sjis,--mime,--base64  convert for named code>

C< --jis-input,--euc-input,--sjis-input,--mime-input,--base64-input assume input system>

C< -- ignore rest of -option>

C< --help>

C< --version>
