I think its worth pointing out that the Rust code is more broken than the Go code in this example. Because Rust is trying to come up with a sane way to display the filename (a) it prevents users from using encodings the language designers did not anticipate and (b) it prevents the solution from integrating with other system tools. For instance, you can't run `rm "$(rust_program)"`, but you can with the Go solution.

But discussing any of this means you've missed the point of languages like Go. Instead of arguing about the best way to to represent pathnames that aren't a valid byte sequence under $PREFERRED_LOCALE, we should be talking to our customers and solving their problems.
