... or if you can't type ö on your keyboard, at least write “oe“ as in Goedel. Just a little hint from a German native here. (Same goes for ae and ue instead of ä and ü).
Interestingly that's getting less common in Scandinavia. It's the "proper" transliteration, but many people with names like Søren prefer to anglicize them as Soren rather than Soeren, if anglicization is needed. Not universally, but it's my impression of the trend.
