Support A typo/variation of this type that seems to have "taken on a life of it's own" (as the Google results above show) can be mentioned in the body of the article. I don't see why his legal name as the title of the article wouldn't be uncontroversial. The fact that en.wiki article on him has been titled this way for years probably only helped this version propagate. Re: British press. From what I've seen it, for example, nearly universally drops diacritics of diacriticized European names (Czech, Latvian, etc.) a practice that is avoided in publications that aim to be viewed as works of reference. Latvian press, for example, too can be seen having glaring misspellings and questionable punctuation, it is up to wiki editors to be able to differentiate what can be taken away from it and what is just a consequence of a news article being thrown together hastily.
