使用正则表达式匹配utf-8编码的任意汉字 [英] Use regular expression to match ANY Chinese character in utf-8 encoding

问题描述

比如我想把一个m组成的字符串匹配到n个汉字，那么我可以使用:

For example, I want to match a string consisting of m to n Chinese characters, then I can use:

[single Chinese character regular expression]{m,n}

是否有单个汉字的正则表达式，可以是任何存在的汉字?

Is there some regular expression of a single Chinese character, which could be any Chinese characters that exists?

推荐答案

匹配中文(好吧，CJK)字符的正则表达式是

The regex to match a Chinese (well, CJK) character is

p{script=Han}

可以简单地理解为

p{Han}

这假设您的正则表达式编译器满足要求RL1.2来自UTS#18的属性Unicode 正则表达式.Perl 和 Java 7 都符合该规范，但许多其他版本不符合.

This assumes that your regex compiler meets requirement RL1.2 Properties from UTS#18 Unicode Regular Expressions. Perl and Java 7 both meet that spec, but many others do not.
