NAME
       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
       Unicode base language code (two or three-letter).  For example,
       "Unicode::Collate::Locale->new(locale => 'FR')" returns a collator
       tailored for French.
       $locale_name may be suffixed with a Unicode script code (four-letter),
       a Unicode region code, a Unicode language variant code. These codes are
       case-insensitive, and separated with '_' or '-'.  E.g. "en_US" for
       English in USA, "az_Cyrl" for Azerbaijani in the Cyrillic script,
       "es_ES_traditional" for Spanish in Spain (Traditional).
       If $locale_name is not available, fallback is selected in the following
       order:
           1. language with a variant code
           2. language with a script code
           3. language with a region code
           4. language
           5. default
       Tailoring tags provided by "Unicode::Collate" are allowed as long as
       they are not used for "locale" support.  Esp. the "table" tag is always
       untailorable, since it is reserved for DUCET.
       E.g. a collator for French, which ignores diacritics and case
       difference (i.e. level 1), with reversed case ordering and no
       normalization.
           Unicode::Collate::Locale->new(
               level => 1,
               locale => 'fr',
               upper_before_lower => 1,
               normalization => undef
           )
       Overriding a behavior already tailored by "locale" is disallowed if
       such a tailoring is passed to "new()".
           Unicode::Collate::Locale->new(
               locale => 'da',
               upper_before_lower => 0, # causes error as reserved by 'da'
           )
       However "change()" inherited from "Unicode::Collate" allows such a
       tailoring that is reserved by "locale". Examples:
           new(locale => 'ca')->change(backwards => undef)
           new(locale => 'da')->change(upper_before_lower => 0)
           new(locale => 'ja')->change(overrideCJK => undef)
   Methods
       "Unicode::Collate::Locale" is a subclass of "Unicode::Collate" and
       methods other than "new" are inherited from "Unicode::Collate".
       Here is a list of additional methods:
       "$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.
       "$Collator->locale_version"
           (Since Unicode::Collate::Locale 0.87) Returns the version number
           (perhaps "/\d\.\d\d/") of the locale, as that of Locale/*.pl.
           Note: Locale/*.pl that a collator uses should be identified by a
           combination of return values from "getlocale" and "locale_version".

       Locales according to the default UCA rules include chr (Cherokee), de

       (Georgian), ms (Malay), nl (Dutch), pt (Portuguese), st (Southern
       Sotho), sw (Swahili), xh (Xhosa), zu (Zulu).
       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.
       [3] zh__pinyin and zh__stroke: implemented alt='short', where a smaller
       number of ideographs are tailored.
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.
