Dear Maintainer, For some reason it seems when hyperlinks are copy-pasted on the CLI/terminal emulator it sometimes deletes or adds letters to it. For e.g. I had been trying - $ youtube-dl -c -f 22 QPbWC_ZinNE Now the whole URL from where the hash been taken us - https://www.youtube.com/watch?v=QPbWC_ZinNE&list=PLHqSuWJSw8SAbt-xWXQ_dPkMvvaOJei47&index=8&t=0s Now for some reason when I delete or backspace keys I get at times the hash like - $youtube-dl -c -f 22 htQPbWC_ZinNE OR $youtube-dl -c -f 23 bWC_ZinNE&i such kind of things keep happening and I have to do it couple of times to get it right. The best way is to copy and paste it to featherpad and then copy and paste the results. It seems to work but that is only a workaround. Please let me know if you need any more info.
