Quick currency detection script I wrote while making http://jamedjo.github.io/Converter/ to test out angularjs

currency.js

function defaultCurrencyFromLanguage(){
  var lang = window.navigator.userLanguage || window.navigator.language;
  var symbol = "$";
  if(/gb|uk|tr|je|ta|gs|gg|im|sd|sl|vg|cy|eg|fk|gi|lb|sh|ac|ss|sd|sy/i.test(lang)) {
    symbol = "£";
  }
  else if(/me|sk|ea|gf|tf|bl|mf|ie|ee|re|it|mc|si|de|es|at|yt|gp|pm|cy|pt|fr|gr|ic|be|ad|fi|lu|va|mt|sm|mq|nl|ax|cs/i.test(lang)) {
    symbol = "€";
  }
  else if(/cn|jp|fm|sj/i.test(lang)) {
    symbol = "¥";
  }
  else if(/in|bt|pk|bd|iq|np|mu|sc|lk/i.test(lang)) {
    symbol = "₨";
  }
  else if(/kp|kr/i.test(lang)) {
    symbol = "₩";
  }
  else if(/li|ch/i.test(lang)) {
    symbol = "CHF";
  }
  else if(/is|nb|nn|sv|et|da/i.test(lang)) {
    symbol = "kr";
  }
  else if(/ru/i.test(lang)) {
    symbol = "руб";
  }
  return symbol;
}
