Non-ASCII File Names

[Hopkins]

When I open an edit an epub that has a non-ASCII file name (i.e. 副本保存失敗.epub) I cannot save it. I get the following error:

calibre, version 3.14.0
ERROR: Could not save: Saving of the book failed. Click "Show details" for more information. You can try to save a copy to a different location, via File->Save a copy

Traceback (most recent call last):
  File "site-packages\calibre\gui2\tweak_book\save.py", line 199, in process_save

  File "site-packages\calibre\utils\filenames.py", line 487, in atomic_rename
error: (123, 'MoveFileEx', 'The filename, directory name, or volume label syntax is incorrect.')

I am only able to save a copy using an ASCII name.

Is there an option in the editor to allow using non-ASCII file names?

You can use non-ascii filenames on operating systems other than windows or on utf-8 based windows systems.

Right, this is a Windows 10 US Version. It supports non-ASCII names in the file manager. I guess I'm assuming it is a UTF-8 based system.

Some users of the Chinese Conversion plugin in the Calibre editor have:

1. opened their non-ASCII named EPUB files via the "Open book" menu
2. made changes to the text
3. attemped to save (or save a copy) of the book using the same non-ASCII title

They are confused when they get an error since the OS supports non-ASCII file names and the editor successfully opened the non-ASCII named file. I'm currently recommending they do a "Save a copy" using a temporary ASCII name and then rename it back to the desired name. It's a bit of a kludge.

Supporting non-ascii filenames does not mean a system is utf-8. Windows has a mess of legacy encodings it uses (google windows code page).

This should take care of it: https://github.com/kovidgoyal/calibr...2f7e27e9cb768f

Thanks!
