# StringDecoder

    Stability: 2 - Stable

To use this module, do `require('string_decoder')`. StringDecoder decodes a
buffer to a string. It is a simple interface to `buffer.toString()` but provides
additional support for utf8.

    const StringDecoder = require('string_decoder').StringDecoder;
    const decoder = new StringDecoder('utf8');

    const cent = new Buffer([0xC2, 0xA2]);
    console.log(decoder.write(cent));

    const euro = new Buffer([0xE2, 0x82, 0xAC]);
    console.log(decoder.write(euro));

## Class: StringDecoder

Accepts a single argument, `encoding` which defaults to `'utf8'`.

### decoder.end()

Returns any trailing bytes that were left in the buffer.

### decoder.write(buffer)

Returns a decoded string.
