This in not true for everywhere that uses the Euro, unsurprisingly because that encompasses a large linguistic area. I know for a fact France doesn't pronounce it that way.
I've racked my brain trying to write it in a good enough approximation, but honestly the "eu" sound doesn't have a match in most English accents, and neither does the "r", so it wouldn't make much sense trying to write it down in English. Youtube will give you hundreds of videos pronouncing it correctly if you want to check!
