When a filename contains any blank space, it returns "No such file or directory"

[Baytars]

Not a big deal, I can replace every blank space in the filename with an underscore, but if you can fix this issue, that'll save my work. Your batch pdf unlocker worked gracefully, anyway! Thanks for your work!

For example, if there's a pdf file named "acute renal.pdf", it will return
open ./output/acute: No such file or directory
open ./output/renal.pdf: No such file or directory

@Baytars hope this works: https://github.com/hupili/unlock-pdf
