A permanent fix is being developed. however, for now there is a workaround:
The additional (cursor-like) character must be deleted before running the 11.3 script.
A specific way in deleting the character is to go to beginning of the name, press the ‘Shift’ key and the ‘Right Arrow’ key together and press the ‘Delete’ key.
2. Using Excel ‘Paste Special’ > ‘Value’ or pasting the file name to Notepad and copying it back to the script does not work, too.
