Percent encoded characters in URL gives error in browser

Question

I'm having problem with URL's that include special characters. The rendered HTML if I use NavigateUrl='Eval("website")' is this:

<a href="http://www.v%c3%a4rnamo.nu">www.värnamo.nu</a>

If I try to encode it like this NavigateUrl='<%# HttpUtility.HtmlEncode(Eval("website")) %>' I get this output, which doesn't work either.

<a href="http://www.v&/"288;rnamo.nu">www.värnamo.nu</a>

I tried setting charset in the meta tag to UTF-8 and iso-8859-1, but it didn't help, and I don't think it has to do with that either.

Try clicking this link: http://www.v%c3%a4rnamo.nu and you'll get the same response.

Anything else I can try?

I actually got this to work now. I used the code at this LINK

In my aspx page I use this in the NavigateUrl property:

NavigateUrl='<%# idnMapping(Convert.ToString(Eval("website"))) %>'

Which calls the function:

public static string idnMapping(string text) {
    System.Globalization.IdnMapping idn = new System.Globalization.IdnMapping();
    return idn.GetAscii(text);
}

Now when I view the html I see

<a href="http://xn--vrnamo-bua.nu">www.värnamo.nu</a>

And clicking this link will open the page correctly.
