Unicode upper/lower casing is now used when UCP is set, even if UTF is not set. 

This is not yet documented, and it not yet implemented in JIT.

@ -66,6 +66,11 @@ recurse function in JIT.
17. Fix a crash which occurs when the character type of an invalid UTF
character is decoded in JIT.
18. Changes in many areas of the code so that when Unicode is supported and
PCRE2_UCP is set without PCRE2_UTF, Unicode character properties are used for
upper/lower case computations on characters whose code points are greater than
127. Documentation is not yet updated. JIT is not yet updated.
