You can't get null bytes from a command-line argument. And going by >>44991638 it's common to not use OsString when accepting command-line arguments, because std::env::args yields Strings, which means that probably most Rust programs that accept filenames on the command line have this bug.

Rust String can contain null bytes! Rust uses explicit string lengths. Agree though that most OS wouldn't be able to pass null bytes in arguments though.

Right, but it can't contain invalid UTF-8, which is valid in both command-line parameters and in filenames on Linux, FreeBSD, and other normal Unixes. See my link above for a demonstration of how this causes bugs in Rust programs.
