The most complete regular check of Chinese characters: only Chinese characters are allowed, dots are allowed, extended Chinese characters are allowed, rare characters, such as Chinese characters like 䶮

Here we only talk about regular verification of Chinese names. If you need more comprehensive verification, please see another blog:

The most complete js front-end and back-end common verification method for Chinese names (with dots) in the whole network

Still the same style, always direct, no nonsense, start:

1: Verify pure Chinese characters (length is 2-6 digits):

/^([\u4e00-\u9fa5]{2,6})$/gi.test('要校验的汉字')

2: Verify Chinese characters with dots (you need to deal with various dots, please see the blog at the beginning of the article)

Allow 2-5 Chinese characters before and after the point

/^[\u4E00-\u9FA5]{2,5}([\u25CF\u00B7][\u4E00-\u9FA5]{2,5})*$/gi.test('待校验汉字')

 

 3: With rare characters, such as: 䶮 (Unicode code: 4DAE)

/^[\u9FA6-\u9FCB\u3400-\u4DB5\u4E00-\u9FA5]{2,5}([\u25CF\u00B7][\u9FA6-\u9FCB\u3400-\u4DB5\u4E00-\u9FA5]{2,5})*$/gi.test('待校验汉字');

Before and after adding Unicode codes of rare characters:

 

For the range of unicode Chinese character codes, the basic Chinese characters are generally enough, and the extension A can be brought at most, and the latter will not appear in the usual and personal names, because the system of the Civil Affairs Bureau may not be able to type it out.
