Enclosing it within quotes seems like defeat. Edit: You can assign the property to be without quotes using a bit of a hack, you just can't call it. var o = {}; // Creates a new object Object.defineProperty(o, "（╯°□°）╯︵┻━┻", {value : "Please respect tables! ┬─┬ノ(ಠ_ಠノ)"}); //=> o = {（╯°□°）╯︵┻━┻: "Please respect tables! ┬─┬ノ(ಠ_ಠノ)"} Trying to call o.（╯°□°）╯︵┻━┻ returns an error though.
