Germany != Europe.

The French use « », Italians use ‘regular’ “quotes”, etc.

Strangely enough, this is the first time I see your style of quote, in two decades on the Internet.

Yeah I’m surprised at how rare this is to see. I guess that means all Germans don’t follow this convention?

I believe it should be double, „like this“, not single quotes.

Other countries use it too. I'm pretty sure that Spain does.

Nope, Spain uses « » (though mostly only in formal writing these days) or English-style quotes.
