Enum member named with a Unicode escape emits the raw escape text

[mds-ant]

Steps to reproduce

main.ts:

enum E {
  \u0041 = 1,
}
const a = E.A;

tsgo main.ts

Behavior with typescript@6.0

"use strict";
var E;
(function (E) {
    E[E["A"] = 1] = "A";
})(E || (E = {}));
const a = E.A;

Here, a evaluates to 1.

Behavior with tsgo

"use strict";
var E;
(function (E) {
    E[E["\\u0041"] = 1] = "\\u0041";
})(E || (E = {}));
const a = E.A;

Here, a evaluates to undefined.
