Unicode range of Chinese Characters

// Note:

Regular Expression matching Chinese characters: [\ u4e00-\ u9fa5]

In QT, the following regular expression can be used for verification:

// CJK Unified ideographic characters
Qregexp rx ("[\ u4e00-\ u9fa5] + ");
Qvalidator * validator = new qregexpvalidator (RX, this );
UI-> lineeditcustom-> setvalidator (validator );

 

This contains CJK Unified ideographic characters (probably basic Chinese characters), which is basically enough.

To view all Unicode, you can use the character ing table that comes with ubuntu.

I searched for the Unicode range of Chinese characters on the Internet and generally gave "U + 4e00 .. u + 9fa5 ". But in fact, this range is incomplete, and even the basic fullwidth (Chinese) punctuation is not included. Based on the latest Unicode 5.0 version, sort it out as follows: Note: In most application scenarios, we can use only (1), (2), (3), (4), (5) sets as the basis for CJK judgment. 1) Standard CJK text Http://www.unicode.org/Public/UNIDATA/Unihan.html Code Point Range Block name Release U + 3400 .. u + 4db5 CJK uniied ideographs extension 3.0 U + 4e00 .. u + 9fa5 CJK uniied ideographs 1.1 U + 9fa6 .. u + 9fbb CJK uniied ideographs 4.1 U + f900..
