Support casing characters which map into multiple code points (bug#24603) Implement unconditional special casing rules defined in Unicode standard. Among other things, they deal with cases when a single code point is replaced by multiple ones because single character does not exist (e.g. ‘fi’ ligature turning into ‘FL’) or is not commonly used (e.g. ß turning into SS). * admin/unidata/SpecialCasing.txt: New data file pulled from Unicode standard distribution. * admin/unidata/README: Mention SpecialCasing.txt. * admin/unidata/unidata-get.el (unidata-gen-table-special-casing, unidata-gen-table-special-casing--do-load): New functions generating ‘special-uppercase’, ‘special-lowercase’ and ‘special-titlecase’ character Unicode properties built from the SpecialCasing.txt Unicode data file. * src/casefiddle.c (struct casing_str_buf): New structure for representing short strings used to handle one-to-many character mappings. (case_character_imlp): New function which can handle one-to-many character mappings. (case_character, case_single_character): Wrappers for the above functions. The former may map one character to multiple (or no) code points while the latter does what the former used to do (i.e. handles one-to-one mappings only). (do_casify_natnum, do_casify_unibyte_string, do_casify_unibyte_region): Use case_single_character. (do_casify_multibyte_string, do_casify_multibyte_region): Support new features of case_character. * (do_casify_region): Updated to reflact do_casify_multibyte_string changes. (casify_word): Handle situation when one character-length of a word can change affecting where end of the word is. (upcase, capitalize, upcase-initials): Update documentation to mention limitations when working on characters. * test/src/casefiddle-tests.el (casefiddle-tests-char-properties): Add test cases for the newly introduced character properties. (casefiddle-tests-casing): Update test cases which are now passing. * test/lisp/char-fold-tests.el (char-fold--ascii-upcase, char-fold--ascii-downcase): New functions which behave like old ‘upcase’ and ‘downcase’. (char-fold--test-match-exactly): Use the new functions. This is needed because otherwise fi and similar characters are turned into their multi- -character representation. * doc/lispref/strings.texi: Describe issue with casing characters versus strings. * doc/lispref/nonascii.texi: Describe the new character properties.
