Pure JavaScript Iconv for Japanese encodings.
- This module supports the encodings commonly used in the Japanese Language:
Shift_JIS(CP932), ISO-2022-JP(-1), EUC-JP, UTF8, UNICODE(UCS2) conversion. - Pure Javascript, no need to compile.
- Much faster than node-iconv.
$ npm install jconv
For example simply convert from EUC-JP to Shift_JIS:
var jconv = require( 'jconv' );
var SJISBuffer = jconv.convert( EUCJPBuffer, 'EUCJP', 'SJIS' );
Also available iconv-lite syntax:
var str = jconv.decode( buffer, fromEncoding );
var buf = jconv.encode( 'string', toEncoding );
-
jconv( input, fromEncoding, toEncoding )
-
jconv.convert( input, fromEncoding, toEncoding )
input
{Buffer} or {String}fromEncoding
,toEncoding
{String}:
Shift_JIS(SJIS), ISO-2022-JP(JIS), EUCJP, UTF8, UNICODE(UCS2, UTF16LE) are available.return
{Buffer}
-
jconv.decode( inputBuffer, fromEncoding )
return
{String}
-
jconv.encode( inputString, toEncoding )
return
{Buffer}
-
jconv.encodingExists( encodingName )
return
{Boolean}

Supported: Shift_JIS(CP932), ISO-2022-JP(-1), EUC-JP, UTF8, UNICODE(UCS2).
-
Supported Windows Dependent Characters <-> JIS Conversion.
(problem details) -
"JIS X 0208", "JIS X 0212" and "CP932" have the Unicode Mapping Table Differences, so the specific characters ( ~¢£∥ etc... ) cannot be round-trip converted by default.
This module corrects this difference as much as possible when converting.
