If I do this, then I guess it becomes my responsibility to use the
correct "le" or "be" suffix when I later decode these bytes back into
Unicode code points.

Are there Windows bobby-traps that I need to watch out for because of
this? I already know that the code pages that cmd.exe uses have
caused me some grief in displaying (or not displaying!) code points
