After installing swirl and loading it into Rstudio I received this message:
Do you want to set the language to Chinese traditional?(y/n)
When I say no I then get this:
| Welcome to swirl! Please select where you want to sign in with.
1: Google 2: Facebook 3: Classroom
After logging in via google (I got redirected to what seemed to be a genuine google login page, with my various google accounts pre-loaded, I just had to pick one) and loading a course, the text is all in chinese anyway.
I found a couple of other people with this problem but no answer as to how it happens.

I'm running Rstudio on a Mac.
Any clues?
