chrome's extension api for downloads has the same limitation

filenames that are reserved names on windows (like NUL) or contain characters that are reserved on windows are refused with "Invalid filename", even on platforms and filesystems that don't have the same limitations

this might be desirable for enforcing portability in extensions, but the thing isn't mentioned in the documentation[1] for the api so you had to know about it beforehand (like most extension devs, probably) or find out the hard way when some of your downloads unexpectedly fail (like me)

i was using it on linux in a personal extension i wrote, and i thought it was silly that i had to add extra code to further sanitize and mangle the filenames for an OS i don't even use
