I have checked the exams platform, I looked at Methodenlehre I, but I could not find where i can download zip

On tucexam? You must go to "Bewertungen" and then on the right-hand-side there should be some export; alternatively go to archive. It is a bit hidden.

I think it is due to "lagemaßeDavisS2024", german letter in file name, it gives a problem with unzipping

Oh no; once again, I guess I forgot about that. Can we give a meaningful error?

there is another issue, i am working on it

The problem was with results for Ordering type, when candidate did not provide the answer at all. I have fixed it.
Can you check again and give me your error message now?

Great! Works for me. Is this an additional problem to ß? Or was ß not a problem in the first place?

if you do not have an error, it means that problems with german letters are only on my side (i think due to win)

Great! Works for me. Is this an additional problem to ß? Or was ß not a problem in the first place?

i had both errors: 1) with incorrect parsing Ordering outcomes 2) with german letter in file name.
The first is solved, the second i still have

I have no errors. Ok, I see. Would it be an option to replace these values during processing? I am not so much concerned for our data since we stopped using umlauts, but for old data or other people's data it could still be a problem. If it is not possible, we could just give a more meaningful error message. It is not high priority though.

I added checker that stops processing and gives a file name. Can you launch it again? I am curious would it give you an error or not? If it stops on your side, I change checker to warning message

I get no error.

in cases like mine a user gets this message
we can close this

We could leave it open; if we have time we can try to rename the files automatically.
