When you want to change the encoding you always go from one into another. So you might go from Mac Roman to UTF-8 or from ASCII to UTF-8.

It's as important to know the desired output encoding as the current source encoding. For example if you have Mac Roman and you decode it from UTF-16 to UTF-8 you'll just make it garbled.

If you want to know more about encoding this article goes into a lot of details:

The npm pacakge encoding which uses node-iconv or iconv-lite should allow you to easily specify which source and output encoding you want:

var resultBuffer = encoding.convert(nameString, 'ASCII', 'UTF-8');

I d recommend using the Buffer class  var someEncodedString   Buffer from  someString    utf-8     This avoids any unnecessary dependencies that other answers require  since Buffer is included with node js  and is already defined in the global scope
