Noticed that if Unicode/foreign characters are in the video title the final DASH output files weren't muxing together when using the title as filename, instead the video and audio files are left separate.

If --restrict-filenames is used the files can be muxed, but it would be better if Unicode titles could be preserved by default.

Output using this video:
