Import CSV with special characters in image filenames

Hi
I’m migrating blogposts from wordpress and in 90% of the time it works perfectly to import CSV.
Problem occurs when the characters æ å ø has been used in the image files.
Url becomes something like: https:://www…/kjøre.jpg (kjøre.jpg being the file on server it tries to download.
This fails. Curious thing is that the CMS import preview does show these images before import, but after import it fails to import these and leave it blank, importing all the other content but will not download the image. When making the field a “required field” theres a message saying these posts could not be imported.

Thanks for any help
