UTF-8 Everywhere
>  In the UNIX world, narrow strings are considered UTF-8 by default almost everywhere. Because of that, the author of the file copy utility would not need to care about UnicodeIt couldn’t be further from the truth. Unix paths don’t need to be valid UTF-8 and most programs happily pipe the mess through into text that should be valid. (Windows filenames don’t have to be proper UTF-16 either)Rust is one of the few programming languages that correctly doesn’t treat file paths as strings.
