As someone with "ø" in my name I have long since accepted that much of the world is not able to spell my name correctly and moved on. There is no point in investing emotional capital in things that won't be fixed for years to come. I'm perfectly fine with "ø", "oe", "ö", and "o".

The first time I was credited in the foreword of a book published in the US my name was spelled with "\x" instead of "ø".

And it could have been worse. I could have been asian or persian. In which case my name would most likely have many westernized representations.

Worry about something of substance.
