screenshots of a browser where your screenshots are automatically named by the application window you're taking a screenshot of. if that tab is an article or forum post or anything that has an emoji in its title, you're getting emojis in the filename. you only find out when you go to find the screenshot later and it's missing. fun stuff
I'm usually not a "you have to go the hard way before going the easy way"-guy, and I started the easy way actually, but using CLI every definitely changes the way you name your files.
And I can't see (and don't want to) how you would manage files through CLI that contains emojis in their name...
I use YouTube-dl on Reddit, so the headline becomes the file name. Lots of emojis in Reddit titles. On the “nature is fucking lit” subreddit, it seems to be a rule to start your title with a fire emoji.
