Redirecting to non-ASCII URL

[miloush]

public IAction Index()
{
    return Redirect(Url.Content("~/ů"));
}

throws InvalidOperationException: Invalid non-ASCII or control character in header: 0x016F with no user code on stack.

The framework decided to put that URL into HTTP header which changed its encoding requirements, so I would expect it to fulfil them. Users might not know or care how the redirect is done and it is not clear what header is the error about.
