+# Encoding
+
+**encoding** is a simple wrapper around [iconv-lite](https://github.com/ashtuchkin/iconv-lite/) to convert strings from one encoding to another.
+
+[![Build Status](https://secure.travis-ci.org/andris9/encoding.svg)](http://travis-ci.org/andris9/Nodemailer)
+[![npm version](https://badge.fury.io/js/encoding.svg)](http://badge.fury.io/js/encoding)
+
+Initially _encoding_ was a wrapper around _node-iconv_ (main) and _iconv-lite_ (fallback) and was used as the encoding layer for Nodemailer/mailparser. Somehow it also ended up as a dependency for a bunch of other project, none of these actually using _node-iconv_. The loading mechanics caused issues for front-end projects and Nodemailer/malparser had moved on, so _node-iconv_ was removed.
+
+## Install
+
+Install through npm
+
+    npm install encoding
+
+## Usage
+
+Require the module
+
+    var encoding = require("encoding");
+
+Convert with encoding.convert()
+
+    var resultBuffer = encoding.convert(text, toCharset, fromCharset);
+
+Where
+
+-   **text** is either a Buffer or a String to be converted
+-   **toCharset** is the characterset to convert the string
+-   **fromCharset** (_optional_, defaults to UTF-8) is the source charset
+
+Output of the conversion is always a Buffer object.
+
+Example
+
+    var result = encoding.convert("ÕÄÖÜ", "Latin_1");
+    console.log(result); //<Buffer d5 c4 d6 dc>
