I've just installed these changes:
o lisp/case-table.el
Add set-upcase-syntax and set-downcase-syntax, modify
th other function to maintain upcase table.
o lisp/international/characters.el, lisp/international/latin-5.el:
Setup cases of GREEK-FINAL-SIGMA, Y-WITH-DIAERESIS,
I-WITH-DOT-ABOVE, DOTLESS-i.
o src/casefiddle.c:
Enable casify_object to change characters of different
byte size. Fix casify_region to work on such a case
correctly.
o src/insdel.c
Fix bugs of replace_range_2.
Now, upcase/downcase commands on the above characters seems
to work correctly.
But, I found case-fold searching and regexp matching doesn't
work as expected. For instance, searching for DOTLESS-i
ignores `i' and `I' but find I-WITH-DOT-ABOVE. On the other
hand, all of the following returns nil:
(staring-match "DOTLESS-i" "i")
(staring-match "DOTLESS-i" "I")
(staring-match "DOTLESS-i" "I-WITH-DOT-ABOVE")
It seems that this behaviour is because compile-pattern is
given a downcase table and search_buffer is given a canon
table and an equiv table, but I still don't understand
the underlying logic of this difference.
