JavaScript + Unicode regexes

Question

How can I use Unicode-aware regular expressions in JavaScript?

For example, there should be something akin to \\w that can match any code-point in Lette

Answer 1

[^\u0000-\u007F]+ for any characters which is not included ASCII characters.

For example:

function isNonLatinCharacters(s) {
    return /[^\u0000-\u007F]/.test(s);
}

console.log(isNonLatinCharacters("身分"));// Japanese
console.log(isNonLatinCharacters("测试"));// Chinese
console.log(isNonLatinCharacters("حمید"));// Persian
console.log(isNonLatinCharacters("테스트"));// Korean
console.log(isNonLatinCharacters("परीक्षण"));// Hindi
console.log(isNonLatinCharacters("מִבְחָן"));// Hebrew
