Unfortunately, even programmers experienced in I18N like Martin, and those with intuition-that-has-the-force-of-law like Guido, express deliberate disbelief on this point. They say that filesystem names and environment variable values are text, which is true from the semantic viewpoint but can't be fully supported by any implementation. With all the focus on backup tools and file managers I think we've lost perspective. They're an important use case, but hardly the dominant one. Please, as a user, if your app is creating new files, do NOT use bytes! You have no excuse for creating garbage, and garbage doesn't help the user any. Getting the encoding right, use the unicode APIs, and don't pass the buck on to everything else. Uhmmm.... That's good advice but doesn't solve any problems :-(. No matter what I create, the filenames will be bytes when the next person reads them in. If my locale is shift-js and the person I'm sharing the file with uses utf-8 things won't work. Even if my locale is utf-8 (since I come from a European nation) and their locale is utf-16 (because they're from an Asian nation) the Unicode API won't work.
