I am trying to allow all special characters and characters using regex.

Currently I have it set up like this

const textValidation = new RegExp("^[A-Za-z0-9_ -]*$");

How would I modfiy this code to allow special characters as well?

Edit: The special character I want to allow are parentheses, this along with all the other characters

    You can do many things to allow _all_ characters (`"."`, `"^"`, ...). But why do you need an expression that doesn't filter anything? – Álvaro González May 02 '23 at 06:41
  • Try using `.`, which will match any character. You may want to add the `s`, or dotall option so it will match a newline as well – mousetail May 02 '23 at 06:41
  • use `/[\w\W]*/` matches any character (\w) or non-word character (\W) – Muthu May 02 '23 at 06:43
  • What *kind* of special characters? If you just want to match everything, use `.`, as suggested by others above, or `[^]`. – InSync May 02 '23 at 07:16
  • If you want to allow all characters and special characters, why do you need a regex then? if you plan to allow all then you don't need a regex check, as everything is allowed. Or am I missing something? – Buttered_Toast May 02 '23 at 07:56
  • Sorry I didn't explain it well in the question but basically I need to allow parentheses it should have been phrased that way – Zubair Amjad May 02 '23 at 08:09

    You can add them to the character class `^[A-Za-z0-9_ ()-]*$` or `^[\w ()-]*$` Note that using `*` will also allow empty strings to match. – The fourth bird May 02 '23 at 08:43

Try something like this.

const myString = "This is a string with special characters like & and #.";
const myRegex = /[\w\W]*/;

if (myString.match(myRegex)) {
  console.log("The string matches the regular expression.");
} else {
  console.log("The string does not match the regular expression.");
}

The regular expression matches any character (\w) or non-word character (\W) zero or more times. The [] brackets define a character set, and the backslash () is used to escape the W to match non-word characters instead of the word characters matched by \w. The * means to match the character set zero or more times.
