You must really hate English place names then (ie. Worcester, Greenwich, Gloucester, etc)
I do. :-)Over here, pronunciations that diverge that far* from the spelling would be considered part of the local dialect and wouldn't enter into the standardized form of the language. Nobody pronounces _Wien_ (Vienna) as if it were spelled _Wern_, except the Viennese, and that only when they speak their dialect.
* "Wooster", "Grennich", "Gloster", right?
