* implement special behavior for Georgian for String#capitalizeduerst2018-12-091-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66300 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* deal with ONIGENC_CASE_IS_TITLECASE flag on lowercase charactersduerst2018-11-251-4/+9
| | | | | | | | | 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. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65971 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* enc/unicode.c: 'a' is bigger than 'A'shyouhei2018-11-161-2/+4
| | | | | | | | | | | | | | | | | | | | | 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. - lib/unicode_normalize/tables.rb: Updated table. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65091 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
