just out of curiosity, can you port the ue back to Germany (or wherever) or will they automatically transform it to ü? (could you change your name in a German speaking country to Mueller et al?)
Goethe is so famous that in Heidelberg, Germany, there is a building with a placard that says, "Goethe almost slept here."
It was an inn and he was supposed to spend the night but was unable to.
