Wow. Coming from DOS times, supporting double quotes in a filename is wild. I _still_ tend not to use whitespaces in filenames!

pretty common on UNIXes; you can also have forward slashes in filenames. They just have to be escaped to differentiate.

I don't know of any Unix that allows forward slashes in file names. On macOS you can use : which is displayed as / in Finder, but in exchange you can't put a : in file names...
