I don't understand this comment. It seems to me that *text* files have
to have an encoding, otherwise you can't interpret the contents as text.
Files, of course, only contain bytes, but to be treated as bytes you
need some way of transforming byte N to char C (or multiple bytes to C),
which is an encoding.
Perhaps you just mean that encodings are not recorded in the text file
To answer Chris' question, you typically cannot include arbitrary
bytes in text files, and displaying them to the user is likewise
problematic. The usual solution is to support some form of
escaping, like \t #x0A; or %0D, to give a few examples.
