var str = "this is a string with speciål chäräcters to remöve";
var badchars = ['å', 'ä', 'ö'];

function removeChars1 (str, badchars) {
  return str.split("").filter((chr) => badchars.indexOf(chr) === -1).join("");
}

function removeChars2 (str, badchars) {
  return str.replace( new RegExp("(" + badchars.join('|') + ")", "g"), "" );
}

Tests:

Using split + filter + join
var final = removeChars1(str, badchars);
Using RegExp global replace
var final = removeChars2(str, badchars);
