At the risk of nit-picking, I think this needs a bit of clarification:
The old 1.02 'stream' classes used to have methods which returned
strings of 16 bit chars - but the way they translated the bytes in
the source data to Unicode characters was too primitive. The new
'reader' classes actually know how to process Utf type data, meaning
that they can cope when they encounter chars which are outside the
usual one byte (seven bit) ASCII range.

So actually it is more accurate to say the 'reader'-based classes
read 8-or-more bit characters, translating them into 16 bit Unicode.

That's good advice. I second that... :-)
