Adding file(upload/scans/audio note) to a folder name with special chars fails with error in loop

Step to reproduce:

Launch the app and login
Tap on "+" button and navigate to create a folder
Enter a folder name with a special character (here: A*)
Click on "Save" ,, it redirect to created folder with special char
Now click "+" button and navigate to "Upload photos and videos"
After select some file click upload and save (here: A*)
Perform scans/audio note record in a created folder name with special chars

Actual result:
Here upload / sync fails with error in loop and it retry to get upload or sync - "409: The request could not be completed due to a conflict with current state of the resource"

Please check upload / sync error with other special chats folder names

Expected result:
Upload should work properly, as it works for android app and in web browser

Note: Please see this fixes as well - There should be an input validation for every prohibited character when entering a folder name.
At the moment there is only a hint displayed if some of the special characters are used (see Folder_create.png).
In case of the screencast, no hint is show.
But even if a hint is show, the user is not kept from creating the prohibited folder name.
This differs from the behavior when renaming a folder. In that case an error is shown,
and the user can't rename the folder (Folder_rename.png).
