JS 中文字符串判断（根据 unicode 编码区间判断）
Determine whether a string is all Chinese(based on unicode range)
$ npm install is-chinese
Chinese range is based on: https://en.wikipedia.org/wiki/CJK_Unified_Ideographs
const isChinese: (str: string, { includePunctuation }?: {
includePunctuation?: boolean | undefined;
}) => booleanimport isChinese from 'is-chinese'
isChinese('中国').should.true();
isChinese('中国ss').should.false();
isChinese('ss').should.false();
isChinese("\uD842\uDFB7").should.true();isChinese("扁担宽，板凳长，扁担想绑在板凳上。") x 15,813,552 ops/sec ±1.28% (98 runs sampled)

isChinese(chars1000WithAscii) false x 2,817,982 ops/sec ±0.36% (90 runs sampled)
Fastest is isChinese("ss扁担宽，板凳长，扁担想绑在板凳上。")
