- Easy API.
- Works on Windows and in sandboxed environments like Cloud9.
- Encoding is much faster than node-iconv (see below for performance comparison).
var iconv = require('iconv-lite'); // Convert from an encoded buffer to string. str = iconv.decode(buf, 'win1251'); // Convert from string to an encoded buffer. buf = iconv.encode("Sample input string", 'win1251');
- All node.js native encodings: 'utf8', 'ucs2', 'ascii', 'binary', 'base64'
- All widespread single byte encodings: Windows 125x family, ISO-8859 family, IBM/DOS codepages, Macintosh family, KOI8 family. Aliases like 'latin1', 'us-ascii' also supported.
- Multibyte encodings: 'gbk', 'gb2313'.
Others are easy to add, see the source. Please, participate. Most encodings are generated from node-iconv. Thank you Ben Noordhuis and iconv authors!
Not supported yet: Big5, EUC family, Shift_JIS.
Comparison with node-iconv module (1000x256kb, on Ubuntu 12.04, Core i5/2.5 GHz, Node v0.8.7). Note: your results may vary, so please always check on your hardware.

Untranslatable characters are set to � or ?. No transliteration is currently supported, pull requests are welcome.
npm install --dev iconv-lite vows # To view performance: node test/performance.js
- Support streaming character conversion, something like util.pipe(req, iconv.fromEncodingStream('latin1')).
- Add more encodings.
- Add transliteration (best fit char).
- Add tests and correct support of variable-byte encodings (currently work is delegated to node).
