Hi there.
I had exactly the same problem, but I just found out how to solve it.
- Check this Mp3Tag help page
https://docs.mp3tag.de/export
Go the bottom or search for the word "BOM" in your browser.
-
Check the screenshot I uploaded. It will show you exactly how to set this on Mp3Tag.
Exit and reopen Mp3Tag, because it only writes the settings on exit. -
After that you should Export all your text files again, with this on your export file:
$filename(my_text_file.txt,utf-8) -
Now you can safely use the Convert from Textfile - Tag, with accented words.
Hope this helps.
