It would be good if 1.2 (and few other places) followed the UTR17,
"Character Encoding Model": <http://www.unicode.org/unicode/reports/tr17/>
There was (and still is) a lot of confusion about the terminology and
UTR17 sets this straight.

That's 96 additional characters. 0x80-0x9F is a C1 region for control
characters (as well as 0x00-0x1F is a C0 region for controls).

The fact that CL standard doesn't define which coded character set is
used has nothing to do with the fact that it predates Unicode. CL is
very carefully worded to allow implementations to chose whatever they
see fit and still be conforming. So the parenthetic remark might
sound offensive to Lisp devotees.
