I've used a domain with "uber" in it for over 20 years, and since the ride sharing service started I have quite a few issues pop up. At least people know how to spell it now.
Über, with an umlaut like the original German word? Or do you spell it Ueber, where the "ue" stands in for an umlaut in character sets which are incapable of reproducing the glyph?
Or do you spell it Uber like the American ride-sharing service, ignoring niceties of pronunciation and trading those for convenience by people who only speak English and don't know German phonology?
EDIT: oh, and reconstructing a word or sentence with missing umlauts etc is very easy to do, at least in my language. You can infer by context if there are ambiguities in 99% of cases.
