double quotes are replaced with single quotes in the filename

[krakrock]

The song I'm trying to download has double quotes in the title, yet when I run it through youtube-dl, it outputs it with single quotes.

How it should be:

Jason Derulo - "Talk Dirty" feat. 2 Chainz (Official HD Music Video)

How it outputs as:

Jason Derulo - 'Talk Dirty' feat. 2 Chainz (Official HD Music Video)

Here's my command:

echo shell_exec('youtube-dl -o "/var/www/dler/audio/%(title)s|' . getID($link) . '.%(ext)s" --write-thumbnail --embed-thumbnail -x --audio-format mp3 "' . $link . '"');

What am I doing wrong?

We remove them in sanitize_filename, it was changed to remove double quotes in #502. I don't know if keeping them would cause some problem.
