+       #   the system; nl_langinfo(CODESET) returns "US-ASCII" in this case.
+       # - The documentation says:
+       #     "... all code that calls BSD system routines should ensure
+       #      that the const *char parameters of these routines are in UTF-8
+       #      encoding. All BSD system functions expect their string
+       #      parameters to be in UTF-8 encoding and nothing else."

+       #     "An additional caveat is that string parameters for files,
+       #      paths, and other file-system entities must be in canonical
+       #      UTF-8. In a canonical UTF-8 Unicode string, all decomposable
+       #      characters are decomposed ..."
+       #   but this is not true: You can pass non-decomposed UTF-8 strings
+       #   to file system functions, and it is the OS which will convert
+       #   them to decomposed UTF-8 before accessing the file system.
+       # - The Apple Terminal application displays UTF-8 by default.
+       # - However, other applications are free to use different encodings:
+       #   - xterm uses ISO-8859-1 by default.
+       #   - TextEdit uses MacRoman by default.
+       # We prefer UTF-8 over decomposed UTF-8-MAC because one should
+       # minimize the use of decomposed Unicode. Unfortunately, through the
