Replace UniCode with space in javascript

Question

I want to replace unicode characters with space. For example, I have this string

This was a very successful meeting.\u000b\u000bWe agreed on several topics:\u000b New strategy\u000b Development ressources\u000b Project optimization

and I want to replace \u000b with space. Currently, I am doing it this way i.e.

var str = "This was a very successful meeting.\u000b\u000bWe agreed on several topics:\u000b";
var replaceStr = str.replace(/[\u000b\u00A0\u1680\u180e\u2000-\u2009\u200a\u200b\u202f\u205f\u3000\u000b-]/g, ' ');

but it's not replacing these unicode characters with space.

Thank you

If I try it out in Browser-Console it works. Are you sure you continue working with replaceStr instead of str? — Paflow

If you are seeing unescaped Unicode code point that probably means that backslash character is escaped in the source. In this case, you can replace the code point with a character it represents:

function unescapeUnicode(raw) {
  return raw.replace(
    /\\u([0-9a-f]{4})/gi,
    (_, c) => String.fromCharCode(Number.parseInt(c, 16))
  )
}

const input = 'This was a very successful meeting.\\u000b\\u000bWe agreed on several topics:\\u000b New strategy\\u000b Development ressources\\u000b Project optimization'

document.body.textContent = unescapeUnicode(input)
