Thanks for letting me know

These words also trigger the same error for me as described in #34

I'm going to close #34 because it seems to be a duplicate of this. I will paste the content into this post.

The word I'm trying to add: 同归于尽 (although this has happened before, I just didn't
bother to report it)
My action: search for the word, click on it, click 'Add card(s)'
Expected behaviour: The word is added to my notes (it works for 99.9% of words still)
Actual behaviour: I get this error message:
