Nonbreaking space and GREP in UXP

How to check if a character is a nonbreaking space in UXP?

if (chars[chars.indexOf(char) - 1].contents === " ") {
            console.log("yes");
          }

I can't use \u00A0 or /~S/. The first one doesn't work, the second can't be used in .jsx UXP.

Correct answer is
if (myCharacter.contents.toString() === "NONBREAKING_SPACE")

You can save time on converting to string and just compare numeric value:

if (myCharacter.contents === 1397645907)
{
    alert("Non Breaking Space")
};

What about using 160 but the hex is \x{00A0}
