The `select_non_existing` lua script selects existing images

When Darktable's library contains images with cyrillic characters in the file path, the select_non_existing lua script selects those images in the library even though they exist on disk and display correctly in Darktable. It is a very similar to my earlier purge_nonexistent_images.bat issue.
It seems like the problem appears only on Windows, because when I tested on MacOS it worked fine.

Here's what gets selected after I click the "select non existing" button:

The expected selection would be:

まず select_non_existing Lua スクリプトを見つけ、Windows でファイルパスをどのようにチェックしているかを確認します。パスにキリル文字を含む既存の画像で問題を再現し、その後、不足している画像だけが選択されることを確認します。可能であれば macOS での動作と比較します。
