When exporting files to my dropbox from goodnotes 5, the zip file produced by goodnotes contains file names with erroneous characters, if the file names contain special characters like æ, ø and å particular to the Danish alphabet.

Unfortunately this renders your app unusuable in conjunction with the LMS that my employer (an upper secondary school) requires that I use for student exercise collection and correction. The students' names are included in all filenames, and quite many of them have names including æ, ø or å.

The zip file produced by goodnotes and exported to Drawbox CAN be opened by Windows 10, but can NOT be zipped again. The special Danish language characters have been replaced by odd, non-alphabet characters.

If I try to zip the unzipped file again, windows says the folder contains files with names containing characters that are not allowed for file names when zipping.

It seems that the procedure, you use in goodnotes 5 to convert corrected files into a zip folder somehow erroneously changes the file names whenever there is a æ, ø, å, Æ, Ø or Å in the file name, changing it to odd, "illegal" characters.

As this makes it impossible for me to use your app for any work purpose, I would be very pleased if you would take the trouble to resolve this issue.

Sincerely
Kim Bertelsen
