💻 Code

class T {
    static readonly ["\t"]: unique symbol;
}
let x = {
    [T["\t"]]: 1
};

🙁 Actual behavior

The type of x is emitted as { [T["\t"]]: number; } in declaration files, making the file invalid since the property does not exist on T

🙂 Expected behavior

The escape should be preserved in the property name.
