Extension fails to process files with special characters (diacritics) in the name

[liv-mrr]

Platform:
Windows

Steps To Reproduce:

1. Install and enable the EasySort extension
2. Add an .nzb with special characters in the name (like Sōmething.Vol.2.nzb)
3. Wait for the download to complete and for the post-processing script to trigger.

Current Behavior:
The extension fails (in logs Error: Post-process-script EasySort for Sōmething.Vol.2.nzb failed (terminated with unknown status))
While individual files without special characters are handled correctly, the parent folder (which inherits the name from the NZB) causes the script to crash because of the diacritics (e.g., "ō")

Expected Behavior:
The extension should correctly handle Unicode/non-ASCII characters in directory names and process the files within them without errors.
