This is the mutley crueh story all over again
https://en.wikipedia.org/wiki/Metal_umlaut
> When Mötley Crüe visited Germany, singer Vince Neil said the band could not figure out why "the crowds were chanting, 'Mutley Cruh! Mutley Cruh!'"
But like those German speakers assumed German orthography, English speakers will assume English orthography when presented with Swedish words.
Only foreign words learned by sound have a chance of getting pronounced correctly, e.g. croissant or Djokovic... maybe even Smörgåsbord?
If there were a British furniture shop operating globally and using placenames for products, British people would have trouble asking the locals for HAWICK (hoik), LOUGHBOROUGH (luffburra), FROME (froom) or YNYSYBWL (anissabul)
They didn't assume German pronunciation without reason. The umlaut dots aren't for decoration in German and ä, ö, ü only sound one way - including in Swedish, which has ä and ö, too. There is no ü in Swedish maybe because the Swedish u sounds like the German ü already (and shifting it further would just make it sound something like an i).
