如何从字符串中删除除西里尔字母/拉丁字母以外的所有符号？

Question

How to delete all symbols except cyrillic/latin alphabet from string?

str = 'детёныш test test ()&^*'
console.log(str.replace(/[^а-яА-Яa-zA-Z]/gi," "))

result:

дет ныш test test

Problem : lost symbol 'ё' in standart а-я range (абвгдеёжзийклмнопрстуфхцчшщъыьэюя)

Answer 1

Probably safer to use the unicode block range for Cyrillic :

str.replace(/[^a-z\u0400-\u04FF]/gi," ");

Here's a snippet:

 const str = 'детёныш test test ()&^*' console.log(str.replace(/[^az\Ѐ-\ӿ]/gi, " "))
