Is there a test case for this?

It got triggered on the file MLHC_lecture/project3/student_submissions/project3/cracra2019/MITBIH dataset/MITBIH - Models (1).ipynb, because it contains unescaped (1) in the filename. I didn't look into how tests are done in this particular project, but I suppose there isn't, since it failed 🤔

The tests are run as part of the CI using pytest. Would you mind having a look? If I remember correctly, there is some code generating some unicode filenames, testing some corner cases. Maybe this could be extended.

I've updated the testcase to cover this, and also checked that it would fail without this change.
