Special characters are not properly recognized

I have created a course on some keyboard shortcuts: https://www.memrise.com/course/1536163/vscode-vim-plugin-shortcuts/

This includes a lot of special symbols e.g.: "^"
For some reason the webapp now does not recognize the symbols I type. If I have a question on “^” and type “^” it will tell me that it is wrong and it expects “^”.
I have copied both the solution and my own symbol to some UTF-8 readers, and both seem to have the same code.

The mobile version seems to work.

Can you check this?

I have the same problem in the https://www.memrise.com/course/18097/an-introduction-to-regular-expressions/ course on every “question” that starts with a “” (e.g. \s, \W, \d, etc…).
