English Characters (ONLY) on form fields!

With some initial testing with Gan, Hakka, Manadarin and
Catonese
chars you can use a simple regex that will not match on the
multibyte
chars. Something like this:

Hope it may help or at least give you a starting point

function englishOnlyChars() {
  var matchString = new RegExp("[a-zA-Z0-9]");

  if (document.myForm.test.value.match(matchString))
   {
     // contains ASCII chars, probably safe to assume not
mixed with
multibyte chars
       return true
     }
  else
   {
   // No ASCII chars found at all, tsk tsk
       return false
     }
 }
