Sorry, I didn't explain clearly. I meant "while checking your patch I 
discovered that the unpatched ed itself does not show correctly (or at 
all) control characters on screen". Just try a line with a null byte or 
a "carriage return".

How can a multi-byte char be recognized as such inside a binary file 
(arbitrary sequence of bytes)?

It is not a problem with your patch. It is simply that ed is too limited 
for what you want it to do.
