Description of your issue, suggested solution and other information

So we have --restrict-filenames option which remove any non-ascii character, but we do not have any option for removing emojis and keep other unicode character. For example, when I'm trying to download https://www.youtube.com/watch?v=TuXyA2sLzmk download will be succeeded but I can not play the file on android due to having emojis on filename.

Again if I use --restrict-filenames it would work smoothly however --restrict-filenames is really bad for non-english video. It would strip full filename where I would like to to youtube-dl support new feature which would respect unicode character while removing emojis and other unsupported by android platform.

BTW, Thanks for this awesome tool :)

Emojis are Unicode characters as well 😄

@Hrxn yes. What I meant is removing emojis and keep rest of the unicode character. Because on android emojis for filename is not supported.

We can do like this in Python:

my_regex = re.compile(r'\d\s*([^☺️|^🙅]+)')
string = "blah xzuyguhbc ibcbb bqw 2 extract1  ☺️ jbjhcb 6 extract2 🙅 bjvcvvv"
m = my_regex.findall(string)```
