The list of encodings that node supports natively is rather short:

ascii
base64
base64url (Node v14+)

hex
ucs2/ucs-2/utf16le/utf-16le
utf8/utf-8
binary/latin1 (ISO8859-1, latin1 only in node 6.4.0+)

If you are using an older version than 6.4.0, or don't want to deal with non-Unicode encodings, you can recode the string:

Use iconv-lite to recode files:

var iconvlite = require('iconv-lite'); var fs = require('fs'); function readFileSync_encoding(filename, encoding) { var content = fs.readFileSync(filename); return iconvlite.decode(content, encoding); }

Alternatively, use iconv:

var Iconv = require('iconv').Iconv; var fs = require('fs'); function readFileSync_encoding(filename, encoding) { var content = fs.readFileSync(filename); var iconv = new Iconv(encoding, 'UTF-8'); var buffer = iconv.convert(content); return buffer.toString('utf8'); }

Simplify the list - it's not the point of the answer. Also, sort it

Updated link to point to master (which will make it more visible if the list changes); made resilient against possibility of total link breakage by copying list of currently-supported encodings into the answer. Feel free to roll back if you disapprove.
