Just to clarify, the cast here "cast(wchar[])" does not convert the bytes
read in to UTF16. If you use a cast here, the bytes must already by in the
order implied by the cast. Thus "cast(wchar[])" is useful if the file is
already  UTF16 encoded file. If the file is, say ASCII or UTF8, and you
need it converted to UTF16, ...

    wchar[] text = std.utf.toUTF16(cast(char[])read("utf08.txt"))
