"You drink tea."
Translation:Du dricker te.
Actually it occurs in many English dialects: https://en.wikipedia.org/wiki/Close_central_rounded_vowel#Occurrence
It's a little complicated, but ʉ̟ː is commonly used for transcribing Standard Swedish in Sweden. There isn't one common standard used everywhere, though, so any comparison is bound to get a little confusing. I can't claim to have seen the /w/ as u, but I don't doubt at all that you've seen it.
The English Wikipedia uses these conventions for Swedish pronunciation: https://en.wikipedia.org/wiki/Help:IPA/Swedish - so I tend to use those when explaining Swedish sounds, as they're often the closest common approximation people may be used to. :)
