Javascript toString() forces ASCII character to change to hex

I’m having a little problem with toString(), when I’m changing the whole function to string to match with regex, toString() changes special characters to HEX, but I need them to stay as they were original in the function as I need to match them later original to original with search and replace function.

Here is an example.

// I'm matching XX.g1("ABV", JU)
function wd () {
 var Dq = document["createElement"](XX.g1("ABV", JU));

}
const regex = / /
const l = wd.toString().match(regex);
let obj = {};
for (let i = 0; i < l.length; i++) {
  const e = l[i]
  console.log(e)
  obj[e] = eval(e)
}

returning XX.g1("Au0017BV", JU) but I need it to be formated as on the picture

{
    "XX.g1("Au0017BV", JU)": "span",
}
