Moben, a Manchester company that makes fitted kitchens, has been going around with an umlaut over the ‘o’ since 1977 but a few years ago someone (who exactly?) managed to persuade a court to stop them using the two dots because it made the company appear to be German which would obviously be a bad thing. Anyway, Möben just won a new ruling and they’ve relaunched with the umlaut back where it belongs, serving an entirely appropriate (although confusing) marketing purpose. Can’t think why they’d want to go around with a redundant umlaut in their brand name but good luck to them.
