title: Can i create a new CultureInfo from a two-character language code?
body: <p>I need to format a number, based on a culture, but all I have is the <code>Accept-Language</code> from the HTTP request, which is a two-letter code like <code>fr</code> (for French)</p>
  
  <p>Is this enough to create a CultureInfo that can handle numbers?</p>
