Latin-1 has nothing to do with it.  There are countless legacy character
sets that use the code points from 32 to 255, and besides, what
maquerades as Latin-1 in various environments rarely is strict iso-8859-1

Bad name also because the legacy character sets are often referred to as
extensions to ASCII up to 255 or below.

Above that they are multi-byte characters, but that doesn't mean they're 
necessarily Unicode, since the CJK legacy character sets are also 
multi-byte.
