Sometimes I also do get very large messages, so it's nice if, when 
converting from, say, Arabic EBCDIC encoding to Unicode, I don't have to 
read the entire message as EBCDIC bytes, then convert the whole thing to 
Unicode at once.  It uses much less memory if I can read, say, 1K of 
EBCDIC bytes, convert them to Unicode characters, append them to a 
string buffer, and repeat until done.

Another thing that I get fairly often (though less often) is a file 
containing many messages separated by some delimiter.  In this case I 
want to read through the file, converting bytes to Unicode characters as 
I go along, and looking for the delimiter until I have a whole message 
in a string.  I don't want to read the whole file at once, because it 
might be far too big.
