Unicode编码范围

引言
       unicode是全世界统一的编码规则,但只规定了各种字符的数字编码(官网:www.unicode.org),具体实现的存储方式有utff-8,utf-16,utf-32等形式,各种形式有不同的存储和与unicode代码的映射规则。


中文字符范围
Unicode CJK 的范围分布在多个区段中,带有 CJK 的区块名中都拥有汉字。但最常用的范围是 U+4E00~U+9FA5,即名
为:CJK Unified Ideographs 的区块,但 U+9FA6~U+9FFF 之间的字符还属于空码,暂时还未定义,但不能保证以后不会被定义。
注1:中文范围 4E00-9FBF:CJK 统一表意符号 (CJK Unified Ideographs)
注2:正则表达式[\u4e00-\u9fa5] 可匹配中文字符,但这种方式并不能根据平台所提供的字符集范围不同而改变。
注3:Unicode 中 U+4E00~U+9FFF 的码表:http://www.unicode.org/charts/PDF/U4E00.pdf
注4:Unicode 码查到所有的字符:http://www.unicode.org/cgi-bin/GetUnihanData.pl
