save_images API function does not work correctly with some characters

[pengyouak]

Description:

If the output dir contains Chinese, the image cannot be saved properly

Can you provide a sample stack trace of what error you get? It would be good to know if this is coming from OpenCV or something PySceneDetect is doing with the paths.

I have tested the PySenceDetect function locally and it can print the path normally. The problem may occur with cv2.iwrite. There is no error output when calling save_images.

cv2.imwrite(get_and_create_path(file_path, output_dir), frame_im, imwrite_param)

[Breakthrough]

I suspected so, I audited the code paths, and PySceneDetect tries to be good about respecting UTF-8 characters in paths. We can probably work around this issue by writing to an in-memory buffer and then saving that to disk separate.
