Any ideas how to get umlauts (ä, ü, ö) in the .docx

[kemuemax]

Hey!
I think the contract builder is great! Thank you so much! But I have a problem for which I cannot find a solution. Umlauts are still displayed correctly on the homepage, but no longer in the .docx. Does anyone have any idea how I could fix this problem? I tried some things with utf-8, but was not working for me. I would like to use the JQuery version; but the problem exists in both versions.
If anyone has a solution, it would be great if you could share it.
Thanks!
