v.1.37.1 on Win 10 (latest updates).

Steps to reproduce:

1. Create new text file tmp.txt. 2. Add "Lorem ipsum dolor sit amet," to the body and save. 3. (Optionally confirm UTF-8 encoding, this does not seem to be an internal encoding issue.) 4. (Optionally -- reopen file to confirm it is working as expected.) 5. Close file and rename to tmp子.txt (or several other Chinese characters... or hangul, such as tmp점.txt... maybe any non-latin?) 6. (Optional: Confirm notepad.exe can open file and display contents.) 7. Open file.

Expected: See original lorem input.

Actual: See empty file. (Can confirm encoding unchanged here.)

7b. Attempt to edit and save: --------------------------- Error --------------------------- Error saving file. Error opening file “<dir>\tmp?.txt”: Input/output error

The file on disk may now be truncated! --------------------------- OK ---------------------------

8. Close file without save. 9. Rename file to just "tmp.txt". Open file, see original input.

I searched for existing issues but might not have used the right keywords, sorry if this is a duplicate.

Hope this is helpful. Thanks for a great program!
