Having issue validating street address with some letters
<p>I am validating a street address with the following function which works fine for all English letters. But it does not accept these letters <code>ö, Ö, ä, Ä</code>. How can I change the following function so that it accepts these letters too?</p>

<pre><code>validateAddress = function (val) {
        var streetRegex = /^[\w+\s]+\d+,\s*[\s\w]+$/;
        if (streetRegex.test(val)) return true;
        else return false;
    }
</code></pre>
