One problem is the multi-byte nature of encodings; one Unicode character can be
represented by several bytes. If you want to read the file in arbitrary-sized
chunks (say, 1k or 4k), you need to write error-handling code to catch the case
chunks (say, 1024 or 4096 bytes), you need to write error-handling code to catch the case
where only part of the bytes encoding a single Unicode character are read at the
end of a chunk. One solution would be to read the entire file into memory and
then perform the decoding, but that prevents you from working with files that

(More, really, since for at least a moment you'd need to have both the encoded
string and its Unicode version in memory.)
