## DESCRIPTION
    "[Unicode::Collate::CJK::GB2312](https://www.chedong.com/phpMan.php/perldoc/Unicode%3A%3ACollate%3A%3ACJK%3A%3AGB2312/markdown)" provides "weightGB2312()", that is adequate for "overrideCJK" of
    "[Unicode::Collate](https://www.chedong.com/phpMan.php/perldoc/Unicode%3A%3ACollate/markdown)" and makes tailoring of CJK Unified Ideographs in the order of CLDR's
    gb2312han ordering.

## CAVEAT
    The gb2312han ordering includes 5 code points in private use area (E2D8..E2DC), that can't
    utilize "weightGB2312()" for collation. For them, use "entry" instead.
