char[] should never be anything other than UTF-8. Similarly, wchar[] is UTF-16, and dchar[] is UTF-32. So, if you're getting something other than UTF-8, it should not be char[]. It should be something more like ubyte[]. If you want to operate on it as char[], you should convert it to UTF-8. std.encoding may or may not help with that. But pretty much everything in D - certainly in the standard library - assumes that char, wchar, and dchar are UTF-encoded, and the language spec basically defines them that way. Technically, you _can_ put other encodings in them, but it's just asking for trouble. - Jonathan M Davis
