Double quote characters turn entire playlist name into "\" [bandcamp:album]

[bryc]

This occurs when attempting to download an album on Bandcamp with names such as "Entropy" EP that contain quotes. I'd expect an output folder name such as Entropy EP or Entropy EP, however for some reason it gives only \ instead, is substituted as _ when written as a folder.

Using this command line:
youtube-dl -v -a urls.txt -i -o "%(playlist)s/%(playlist_index)s - %(title)s.%(ext)s"

It creates a folder called "_" from the "" character, and puts all downloaded files there, so any affected album names will end up there. However on the very first line of the output, it gets it right: "[Bandcamp:album] entropy-ep" Why isn't it using that?

URL to the album is here: https://jstrecords.bandcamp.com/album/entropy-ep

I had the same issue, hence here's one possible fix:
webpage = webpage.replace('\\"', "") (added to the file youtube_dl/extractor/bandcamp.py)

Note: possibly this could be done right before any extraction is performed on the webpage.

Cause of the problem is the \" on the extracted webpage (see below)

... makes the regex exit immediately (see below)

Alternative Fix: use the regex itself to jump the quotes

P.s.: @bryc I think your text command should have quotes too (at least I needed those to replicate your issue), hence:
youtube-dl -v -a urls.txt -i -o "%(playlist)s/%(playlist_index)s - %(title)s.%(ext)s"
