The modern Georgian script is special in that it has an 'uppercase'
variant called MTAVRULI which can be used for emphasis of whole words,
for screamy headlines, and so on. However, in contrast to all other
bicameral scripts, there is no usage of capitalizing the first letter
in a word or a sentence. Words with mixed capitalization are not used
at all.
We therefore implement special behavior for String#capitalize. Formally,
we define String#capitalize as first applying String#downcase for the
whole string, then using titlecase on the first letter. Because Georgian
defines titlecase as the identity function both for MTAVRULI ('uppercase')
and Mkhedruli (lowercase), this results in String#capitalize being
equivalent to String#downcase for Georgian. This avoids undesirable
mixed case.
* enc/unicode.c: Actual implementation
* string.c: Add mention of this special case for documentation
* test/ruby/enc/test_case_mapping.rb: Add two tests, a general one
that uses String#capitalize on some (including nonsensical)
combinations of MTAVRULI and Mkhedruli, and a canary test to
detect the potential assignment of characters to the currently
open slots (holes) at U+1CBB and U+1CBC.
* test/ruby/enc/test_case_comprehensive.rb: Tweak generation of
expectation data.
Together with r65933, this closes issue #14839.

In the function onigenc_unicode_case_map() in enc/unicode.c, deal
with the case that the ONIGENC_CASE_IS_TITLECASE flag is set on
lowercase characters. This is in preparation for Georgian Mtavruli,
which are uppercase but not titlecase, in Unicode 11.0.0.

In ASCII, 'a' is bigger than 'A'. Which means 'A' - 'a' is a negative
number (-32, to be precise). In C, the type of 'a' and 'A' are signed
int (cf: ISO/IEC 9899:1990 section 6.1.3.4). So 'A' - 'a' is also a
signed int. It is `(signed int)-32`.
The problem is, OnigCodePoint is unsigned int. Adding a negative
number to a variable of OnigCodepoint (`code` here) introduces an
unintentional cast of `(unsigned)(signed)-32`, which is
4,294,967,264. Adding this value to code then overflows, and the
result eventually becomes normal codepoint.
The series of operations are not a serious problem but because
`code >= 'a'` holds, we can `(code - 'a') + 'A'` to reroute this.

- common.mk: Change Unicode version to 11.0.0
- enc/unicode/case-folding.rb, enc/unicode.c: Initial changes to deal with
Gregorian Mtavruli. This should bring us up to the same level as e.g.
Python 3.7, by following the Unicode tables exactly. But it will
produce undesirable (mixed-case) results for String#capitalize.
This will be addressed in a later commit.
- enc/unicode/11.0.0, enc/unicode/11.0.0/casefold.h, enc/unicode/name2ctype.h:
Add generated files.

which depend on the Unicode version.

* regparse.c (node_extended_grapheme_cluster): as Unicode 10 has
added Grapheme_Cluster_Break properties to some characters,
remove duplicated ranges for Unicode 9.

(GREEK SMALL LETTERs IOTA/MU, CYRILLIC SMALL LETTER MONOGRAPH UK)
from onigenc_unicode_case_map and simplify code.
* enc/unicode/case-folding.rb: Remove check for U+03B9/U+03BC/U+A64B.
This and the previous few related commits make sure that we won't hit
the equivalent of bug #12990 anymore for future updates of Unicode versions.

at the end of onigenc_unicode_case_map (Bug #12990).
* enc/unicode/case-folding.rb: Add U+A64B to the special cases
03B9 and 03BC. Add a comment pointing to enc/unicode.c.
Change warnings to exceptions for unpredicted cases,
because this would have been more easily noticed
(the warning was not noticed when upgrading to Unicode 9.0.0).
* test/ruby/enc/test_case_comprehensive.rb: Remove temporary
exclusion of U+A64B from testing.

swapcase functionality for titlecase characters. Swapcase isn't defined
by Unicode, because the purpose/usage of swapcase is unclear anyway.
The implementation follows a proposal from Nobu, swaping the case of
each component of a titlecase character individually.
This means that the titlecase characters have to be decomposed.
* enc/unicode.c: Code using the above data.
