If anyone from Framework is reading this: It appears as though the image[1] accompanying the US International keyboard on the US Framework Marketplace[2] is inaccurate. It seems to be an ANSI keyboard with the word 'gr' crudely photoshopped into the right alt key. This is most likely a mistake, as the term 'US International' typically refers to an ISO keyboard. I would humbly suggest that Framework correct the image and clarify whether the keyboard in question is ISO or ANSI.
Our English International keyboard is indeed ANSI. The two differences are "Alt Gr" and a euro symbol (which is missing from that image, and which I've just captured as a bug internally). This is the keyboard layout most popularly used in the Netherlands.
^ edit: To elaborate, I believe ANSI is the correct layout for US International, but unfortunately more often than not, when I ordered US International, I got an ISO layout (n=2 out of 3). This leads me to believe that the term is ambiguous. It can mean either US layout + international labels, or US labels + international layout (the I in ISO).
