Filter bad words with special characters

Question

I use https://www.npmjs.com/package/bad-words and I created regex for special filter characters.

const Filter = require('bad-words');
const badWordsFilter = new Filter({replaceRegex:  /[A-Za-z0-9öÖÇ窺ĞğİıÜü_]/g});
badWordsFilter.addWords(['badword', 'şğ'])

If the word does not contain a Turkish character, it works. But if I write a Turkish character, for example, ş or ğ, it is not filtered.

Is my regex wrong?

I found this code in the documentation:

var filter = new Filter({ regex: /\*|\.|$/gi });
var filter = new Filter({ replaceRegex:  /[A-Za-z0-9가-힣_]/g }); 
//multilingual support for word filtering

Answer 1

You obviously have a problem with the encoding, since your regular expression works from your application, see here: https://regex101.com/r/VpItfH/3/ .
