Unicode::Collate::CJK::Big5 - weighting CJK Unified Ideographs for Unicode::Collate SYNOPSIS
use Unicode::Collate; use Unicode::Collate::CJK::Big5; my $collator = Unicode::Collate->new( overrideCJK => &Unicode::Collate::CJK::Big5::weightBig5 ); DESCRIPTION
"Unicode::Collate::CJK::Big5" provides "weightBig5()", that is adequate for "overrideCJK" of "Unicode::Collate" and makes tailoring of CJK Unified Ideographs in the order of CLDR's big5han ordering. SEE ALSO

Unicode::Collate::Locale - Linguistic tailoring for DUCET via Unicode::Collate SYNOPSIS
use Unicode::Collate::Locale; #construct $Collator = Unicode::Collate::Locale-> new(locale => $locale_name, %tailoring); #sort @sorted = $Collator->sort(@not_sorted); #compare $result = $Collator->cmp($a, $b); # returns 1, 0, or -1. Note: Strings in @not_sorted, $a and $b are interpreted according to Perl's Unicode support. See perlunicode, perluniintro, perlunitut, perlunifaq, utf8. Otherwise you can use "preprocess" (cf. "Unicode::Collate") or should decode them before. DESCRIPTION
This module provides linguistic tailoring for it taking advantage of "Unicode::Collate". Constructor The "new" method returns a collator object. A parameter list for the constructor is a hash, which can include a special key "locale" and its value (case-insensitive) standing for a two-letter language code (ISO-639) like 'en' for English. For example, "Unicode::Collate::Locale->new(locale => 'FR')" returns a collator tailored for French. $locale_name may be suffixed with a territory(country) code or a variant code, which are separated with '_'. E.g. "en_US" for English in USA, "es_ES_traditional" for Spanish in Spain (Traditional), If $localename is not defined, fallback is selected in the following order: 1. language_territory_variant 2. language_territory 3. language__variant 4. language 5. default Tailoring tags provided by "Unicode::Collate" are allowed as long as they are not used for "locale" support. Esp. the "table" tag is always untailorable since it is reserved for DUCET. E.g. a collator for French, which ignores diacritics and case difference (i.e. level 1), with reversed case ordering and no normalization. Unicode::Collate::Locale->new( level => 1, locale => 'fr', upper_before_lower => 1, normalization => undef ) Overriding a behavior already tailored by "locale" is disallowed if such a tailoring is passed to "new()". Unicode::Collate::Locale->new( locale => 'da', upper_before_lower => 0, # causes error as reserved by 'da' ) However "change()" inherited from "Unicode::Collate" allows such a tailoring that is reserved by "locale". Examples: new(locale => 'ca')->change(backwards => undef) new(locale => 'da')->change(upper_before_lower => 0) new(locale => 'ja')->change(overrideCJK => undef) Methods "Unicode::Collate::Locale" is a subclass of "Unicode::Collate" and methods other than "new" are inherited from "Unicode::Collate". Here is a list of additional methods: "$Collator->getlocale" Returns a language code accepted and used actually on collation. If linguistic tailoring is not provided for a language code you passed (intensionally for some languages, or due to the incomplete implementation), this method returns a string 'default' meaning no special tailoring.

Note [1] ja: Ideographs are sorted in JIS X 0208 order. Fullwidth and halfwidth forms are identical to their normal form. The difference between hiragana and katakana is at the 4th level, the comparison also requires "(variable => 'Non-ignorable')", and then "katakana_before_hiragana" has no effect. [2] ko: Plenty of ideographs are sorted by their reading. Such an ideograph is primary (level 1) equal to, and secondary (level 2) greater than, the corresponding hangul syllable. INSTALL
Installation of "Unicode::Collate::Locale" requires Collate/Locale.pm, Collate/Locale/*.pm, Collate/CJK/*.pm and Collate/allkeys.txt. On building, "Unicode::Collate::Locale" doesn't require any of data/*.txt, gendata/*, and mklocale. Tests for "Unicode::Collate::Locale" are named t/loc_*.t. CAVEAT
tailoring is not maximum Even if a certain letter is tailored, its equivalent would not always tailored as well as it. For example, even though W is tailored, fullwidth W ("U+FF37"), W with acute ("U+1E82"), etc. are not tailored. The result may depend on whether source strings are normalized or not, and whether decomposed or composed. Thus "(normalization => undef)" is less preferred. AUTHOR
