trying to convert textarea to hexadecimal in nodejs

About a week ago I found a really nice converter from text to hexadecimal.

However, I didn't test text with newlines. Suddenly my nodejs app returned this: fÚf

instead of:

f

f

the hexadecimal, according to string-functions.com should be 660d0a0d0a66 but my application returns 66da66

here is my "toHex" and "toText" code. This kind of converting isn't my strongest point.

var toHex = function toHex (str) {
  var hex = ''
  for (var i = 0; i < str.length; i++) {
    hex += '' + str.charCodeAt(i).toString(16)
  }
  return hex
}

var toText = function (hexx) {
  var hex = hexx.toString() // force conversion
  var str = ''
  for (var i = 0; i < hex.length; i += 2) {
   str += String.fromCharCode(parseInt(hex.substr(i, 2), 16))
  }
return str
}

edit: when I insert 660d0a0d0a66 directly into my converter it convert to: f f, so there is a problem there as well....
