Since Unicode is a 32-bit character set, Java is not storing the
codepoints directly in all cases, but only the ones that fit; to be fair
those are by far the most common in most environments in which Unicode
is used today.

We are straying, I think, a little far, but, an understanding of
character representation is important to anyone working with text.

Best,
