ABSTRACT

This software has upper compatibility to jcode.pl and multiple inheritance both stable jcode.pl library and active Encode module.

'Ja' is a meaning of 'Japanese' in ISO 639-1 code and is unrelated to 'JA Group Organization'.

The code conversion from 'sjis' to 'utf8' is done by using following table.

http://unicode.org/Public/MAPPINGS/VENDORS/MICSFT/WINDOWS/CP932.TXT

From 'utf8' to 'sjis' is done by using the CP932.TXT and following table.

PRB: Conversion Problem Between Shift-JIS and Unicode

http://support.microsoft.com/kb/170559/en-us

What's this software good for ...

  • jcode.pl upper compatible

  • pkf command upper compatible

  • Perl4 script also Perl5 script

  • Powered by Encode::from_to (Yes, not only Japanese!)

  • Support HALFWIDTH KATAKANA

  • Support UTF-8

  • Hidden UTF8 flag

  • No object-oriented programming

  • Possible to re-use past code and how to

DEPENDENCIES

This software requires perl 4.036 or later.

INTERFACE for newcomers

jacode::convert(\$line, $OUTPUT_encoding [, $INPUT_encoding [, $option]])
 Convert the contents of $line to the specified Japanese
 encoding given in the second argument $OUTPUT_encoding.
 $OUTPUT_encoding can be any of "jis", "sjis", "euc" or "utf8",
 or use "noconv" when you don't want the encoding conversion.
 
 Input encoding is recognized semi-automatically from the
 $line itself when $INPUT_encoding is not supplied. It is
 better to specify $INPUT_encoding, since jacode::getcode's
 guess is not always right. xxx2yyy routine is more efficient
 when both codes are known.
 
 It returns the encoding of input string in scalar context,
 and a list of pointer of convert subroutine and the
 input encoding in array context.
 
 Japanese character encoding JIS X0201, X0208, X0212 and
 ASCII code are supported.  JIS X0212 characters can not
 be represented in sjis or utf8 and they will be replased
 by "geta" character when converted to sjis.
 JIS X0213 characters can not be represented in all.
 
 For perl is 5.8.1 or later, jacode::convert acts as a wrapper
 to Encode::from_to. When $OUTPUT_encoding or $INPUT_encoding
 is neither "jis", "sjis", "euc" nor "utf8", and Encode module
 can be used,
 
 Encode::from_to( $line, $INPUT_encoding, $OUTPUT_encoding )
 
 is executed instead of

 jacode::convert(\$line, $OUTPUT_encoding, $INPUT_encoding, $option).

 In this case, there is no effective return value of pointer
 of convert subroutine in array context.
 
 Fourth $option parameter is just forwarded to conversion
 routine. See next paragraph for detail.
jacode::xxx2yyy(\$line [, $option])
Convert the Japanese code from xxx to yyy.  String xxx
and yyy are any convination from "jis", "euc", "sjis"
or "utf8". They return *approximate* number of converted
bytes.  So return value 0 means the line was not
converted at all.

Optional parameter $option is used to specify optional
conversion method.  String "z" is for JIS X0201 KANA
to JIS X0208 KANA, and "h" is for reverse.
jacode::to($OUTPUT_encoding, $line [, $INPUT_encoding [, $option]])
jacode::jis($line [, $INPUT_encoding [, $option]])
jacode::euc($line [, $INPUT_encoding [, $option]])
jacode::sjis($line [, $INPUT_encoding [, $option]])
jacode::utf8($line [, $INPUT_encoding [, $option]])
These functions are prepared for easy use of
call/return-by-value interface.  You can use these
funcitons in s///e operation or any other place for
convenience.
jacode::jis_inout($JIS_Kanji_IN, $ASCII_IN)
Set or inquire JIS Kanji start and ASCII start sequences.
Default is "ESC-$-B" and "ESC-(-B".  "ASCII start" is used
instead of "JIS Kanji OUT".  If specified in the short form
of one character, and is set by being converted into full
sequence.

-----------------------------------------------
short  full sequence    means
-----------------------------------------------
@      ESC-$-@          JIS C 6226-1978
B      ESC-$-B          JIS X 0208-1983
&      ESC-&@-ESC-$-B   JIS X 0208-1990
O      ESC-$-(-O        JIS X 0213:2000 plane1
Q      ESC-$-(-Q        JIS X 0213:2004 plane1
-----------------------------------------------
jacode::get_inout($line)
Get JIS Kanji start and ASCII start sequences from $line.
jacode::h2z_xxx(\$line)
JIS X0201 KANA (so-called Hankaku-KANA) to JIS X0208 KANA
(Zenkaku-KANA) code conversion routine.  String xxx is
any of "jis", "sjis", "euc" and "utf8".  From the difficulty
of recognizing code set from 1-byte KATAKANA string,
automatic code recognition is not supported.
jacode::z2h_xxx(\$line)
JIS X0208 to JIS X0201 KANA code conversion routine.
String xxx is any of "jis", "sjis", "euc" and "utf8".
jacode::getcode(\$line)
Return 'jis', 'sjis', 'euc', 'utf8' or undef according
to Japanese character code in $line.  Return 'binary' if
the data has non-character code.

When evaluated in array context, it returns a list
contains two items.  First value is the number of
characters which matched to the expected code, and
second value is the code name.  It is useful if and
only if the number is not 0 and the code is undef;
that case means it couldn't tell 'euc' or 'sjis'
because the evaluation score was exactly same.  This
interface is too tricky, though.

Code detection between euc and sjis is very difficult
or sometimes impossible or even lead to wrong result
when it includes JIS X0201 KANA characters.
jacode::init()
Initialize the variables used in this package.  You
don't have to call this when using jocde.pl by `do' or
`require' interface.  Call it first if you embedded
the jacode.pl at the end of your script.

INTERFACE for backward compatibility

jacode::getcode_utashiro_2000_09_29(\$line)
Original &getcode() of jcode.pl.
jacode::cache()
jacode::nocache()
jacode::flushcache()
jacode::flush()
Usually, converted character is cached in memory to
avoid same calculations have to be done many times.
To disable this caching, call jacode::nocache().  It
can be revived by jacode::cache() and cache is flushed
by calling jacode::flushcache().  jacode::cache() and
jacode::nocache() functions return previous caching
state. jacode::flush() is an alias of jacode::flushcache()
to save old documents.
jacode::tr(\$line, $from, $to [, $option])
jacode::tr emulates tr operator for 2 byte code.  Only 'd'
is interpreted as an option.

Range operator like `A-Z' for 2 byte code is partially
supported.  Code must be JIS or EUC-JP, and first byte
have to be same on first and last character.

CAUTION: Handling range operator is a kind of trick
and it is not perfect.  So if you need to transfer `-'
character, please be sure to put it at the beginning
or the end of $from and $to strings.
jacode::trans($line, $from, $to [, $option])
Same as jacode::tr but accept string and return string
after translation.
$jacode::convf{'xxx', 'yyy'}
The value of this associative array is pointer to the
subroutine jacode::xxx2yyy().
$jacode::z2hf{'xxx'}
$jacode::h2zf{'xxx'}
These are pointer to the corresponding function just
as $jacode::convf.

PERL5 INTERFACE for jcode.pl users

Current jacode.pl is written in Perl 4 but it is possible to use from Perl 5 using `references'. Fully perl5 capable version is future issue.

Since lexical variable is not a subject of typeglob, *string style call doesn't work if the variable is declared as `my'. Same thing happens to special variable $_ if the perl is compiled to use thread capability. So using reference is generally recommented to avoid the mysterious error.

SAMPLES

Convert SJIS to JIS and print each line with code name

#require 'jcode.pl';
require 'jacode.pl';
while (defined($s = <>)) {
    $code = &jcode'convert(*s, 'jis', 'sjis');
    print $code, "\t", $s;
}

Convert all lines to JIS according to the first recognized line

#require 'jcode.pl';
require 'jacode.pl';
while (defined($s = <>)) {
    print, next unless $s =~ /[\x1b\x80-\xff]/;
    (*f, $INPUT_encoding) = &jcode'convert(*s, 'jis');
    print;
    defined(&f) || next;
    while (<>) { &f(*s); print; }
    last;
}

The safest way of JIS conversion

#require 'jcode.pl';
require 'jacode.pl';
while (defined($s = <>)) {
    ($matched, $INPUT_encoding) = &jcode'getcode(*s);
    if (@buf == 0 && $matched == 0) {
        print $s;
        next;
    }
    push(@buf, $s);
    next unless $INPUT_encoding;
    while (defined($s = shift(@buf))) {
        &jcode'convert(*s, 'jis', $INPUT_encoding);
        print $s;
    }
    while (defined($s = <>)) {
        &jcode'convert(*s, 'jis', $INPUT_encoding);
        print $s;
    }
    last;
}
print @buf if @buf;

Convert SJIS to UTF-8 and print each line by perl 4.036 or later

#retire 'jcode.pl';
require 'jacode.pl';
while (defined($s = <>)) {
    &jcode'convert(*s, 'utf8', 'sjis');
    print $s;
}

Convert SJIS to UTF16-BE and print each line by perl 5.8.1 or later

require 'jacode.pl';
use 5.8.1;
while (defined($s = <>)) {
    jacode::convert(\$s, 'UTF16-BE', 'sjis');
    print $s;
}

Convert SJIS to MIME-Header-ISO_2022_JP and print each line by perl 5.8.1 or later

require 'jacode.pl';
use 5.8.1;
while (defined($s = <>)) {
    jacode::convert(\$s, 'MIME-Header-ISO_2022_JP', 'sjis');
    print $s;
}

STYLES

Traditional style of file I/O

require 'jacode.pl';
open(FILE,'input.txt');
while (<FILE>) {
    chomp;
    jacode::convert(\$_,'sjis','utf8');
    ...
}

Minimalist style

open(FILE,'perl jacode.pl -ws input.txt | ');

BUGS AND LIMITATIONS

You must use -Llatin switch if you use on the JPerl4. You must use -b switch if you use on the JPerl5.

I have tested and verified this software using the best of my ability. However, a software containing much code is bound to contain some bugs. Thus, if you happen to find a bug that's in jacode.pl and not your own program, you can try to reduce it to a minimal test case and then report it to the following author's address. If you have an idea that could make this a more useful tool, please let everyone share it.
