PUNY

Downloaded files have wrong (punycode) names if they are from pages with Asian text.

Example:
URL:
https://www.facebook.com/tsaiingwen/videos/367525194041724/

Correct Name:
總統2019春節談話

Downloaded File Name:
總統2019春節談話.mp4

I can fix it if it is one or two with this page:
https://www.charset.org/punycode

but imagine I downloaded tens of videos...
