If it is an old, unmodifiable system sending a stream of bytes, it isn't
sending us Unicode is it? Even if you are going from 7 bit ASCII to UTF-8
you might still need to have a transformation process to map it from a
byte stream to text. Of course given all the other possible code pages
those old boxes might be feeding you, this isn't any extra burden.

I'll try to refrain from further comment.
