It looks like Fraktur to me.

Got it in one.

Are you in china? That looks like Canton-ese.

It's a thread of jokes. devoutsalsa started with a joke mixing the two meanings of "capital" using a fake example. I joked that "UniquenessError" isn't the right error, as some countries have more than one capital and two countries have no official capital.

One of those two is Switzerland, which has the official Latin name "Confoederatio Helvetica", leading zinekeller joke that the capital form was "HELVETICA". See https://en.wikipedia.org/wiki/Name_of_Switzerland .

I pretended my implementation of that non-extent programming language generated "Eidgenossenschaft", see https://en.wikipedia.org/wiki/Eidgenossenschaft . As that's a German word, I decided to use a blackletter typeface, specifically, the Fraktur in Unicode which is meant to encode mathematical alphanumeric symbols, then imply that my locale the reason I got a German word.

...and Switzerland is divided into cantons :)
