Description

YouTube has support for adding title (and description) translations for videos. These are added by the uploader. They are shown on YouTube when a translation for that video title exists for the language you use on YouTube.

Example video with translated title

English translated title: Sound Effect - Just Like A Juggler Juggler (Mustafa Tilki)
Original Turkish title: Sound Effect - Hokkabaz Gibiyim Hokkabaz (Mustafa Tilki)

In my use case, I was trying to download a playlist from a channel with titles in my native language (Turkish), but youtube-dl ended up downloading English translated titles for the videos, which I did not want. I would prefer it if it kept the original titles instead.

This could be due to my computer's locale, which is in English; but a switch for setting the locale used when downloading or an output template like org_title which would get the original, non-translated title of the video would be great, in my opinion.
