Encoding is a simple wrapper around node-iconv (https://github.com/bnoordhuis/node-iconv) and iconv-lite (https://github.com/ashtuchkin/iconv-lite/) to convert strings from one encoding to another. If node-iconv is not available for some reason, iconv-lite will be used instead of it as a fallback.

Node.js is an event-based server-side JavaScript engine.
