Description

The "uploader" field of extract_info in youtube-dl's Python version has apostrophes stored as ' instead of the character '. Clearly though apostrophes can be correctly stored because it's so in the "title" field. I haven't checked whether this issue affects other fields or special characters. Here's a short script to test this issue:

#!/usr/bin/python3
import youtube_dl

url="https://www.youtube.com/playlist?list=PL2NN2rktA4yMz3yApgJ33lsRte5NmieJA"

with youtube_dl.YoutubeDL({"verbose": True}) as ydl:
    print(ydl.extract_info(url, process=False))
