Regular Expressions matching Unicode characters (Chinese)

Here are several main non-English character ranges (found on Google ):

2e80 ~ 33ffh: Symbol area of China, Japan, and South Korea. Reception of Kangxi Dictionary heads, China-Japan-South Korea auxiliary departments heads, phonetic symbols, Japanese Kana, Korean Notes, Chinese-Japan-South Korea symbols, punctuation marks, circled or including Rune numbers, months, and Japanese Kana combination, unit, year, month, date, and time.

3400 ~ 4 dffh: Japan and South Korea recognized the expansion of ideographic text area A, a total of 6,582 Chinese and Korean characters.

4e00 ~ 9 fffh: Japan and South Korea recognized the ideographic text area, a total of 20,902 Chinese and Korean characters.

A000 ~ A4ffh: Yi text area, which contains the texts and roots of Yi people in southern China.

Ac00 ~ D7ffh: A combination area of Korean and pinyin. It contains text in Korean Notes.

F900 ~ Faffh: compatible with ideographic text area, a total of 302 Chinese and Korean characters.

Fb00 ~ Fffdh: it is a text expression area that contains a combination of Latin characters, Hebrew characters, Arabic characters, Chinese-Japanese vertices, small characters, halfwidth characters, and fullwidth characters.

For example, to match all Chinese and Korean non-symbolic characters, the regular expression should be ^ [\ u3400-\ u9fff] + $
Theoretically, I copied a Korean file to MSN. co. Ko and found that it was not correct.
Copy A 'handler' to msn.co.jp ..

Then, expand the range to ^ [\ u2e80-\ u9fff] + $. This is all done. This should be the regular expression that matches the Chinese and Japanese characters, including traditional Chinese that we are still using blindly.

The regular expression for Chinese characters should be ^ [\ u4e00-\ u9fff] + $, which is very close to the ^ [\ u4e00-\ u9fa5] + $

Note that ^ [\ u4e00-\ u9fa5] + $ is a regular expression used to match simplified Chinese characters. In fact, traditional Chinese characters are also in the regular expression, I used the tester to test the 'central People's Republic of Korea 'and also passed the test. Of course, ^ [\ u4e00-\ u9fff] + $ is the same result.
