I took Stefan's comment as a general statement, not in the context of
ET. Feeling the need to keep "defending" ET at this point is, to
borrow your words, pretty lame.

The thing is, a user might be happily using ET and call "decode" on
the returned byte strings as long as the files happen to be all ASCII,
without knowing that ET may also return Unicode. Then after some weeks/
months/years a non-ASCII file comes in and the program breaks. As far
as I am concerned, it's a documentation issue, nothing more.
