Revisit how progress bars looks when using --download

This is how the current progress bar looks

⠋ 36% [#######################>------------------------------------------] 35.74MiB 17.34MiB/s ETA 4s

I wonder if getting rid of > and replacing - with . would make it look better. I am also not sure if the spinner is really needed when the download_length is known.

⠋ 39% [##########################.........................................] 39.40MiB 7.22MiB/s ETA 9s

Since the tick character is already Unicode, so I don't think there will be any problem if the progress characters is also Unicode.
