digitalmars.D.learn - latin9 characters in filesystem and command line; std.encoding

This program:

import std.stdio;
import std.file;
void main (string [] args)
    auto entries = dirEntries (args[1], SpanMode.shallow, false);
    foreach (e; entries)
       writeln (e.name);

lists the contents of a directory even if args[1] and the 
filesystem contain names encoded in latin9 (ISO-8859-15). I 
wonder if this behavior can be relied on. Does this use conform 
to the "spirit of D" where strings are assumed to be in in UTF-8 
format [1]?

Second question: Has anybody ever managed to extend std.encoding 
which lacks a latin9 encoding?
