原問題:

I'm currently doing a big switch statement in my javascript to convert

            case 176: char = '\u00B0'; break;
            case 177: char = '\u00B1'; break;
            case 178: char = '\u00B2'; break;
            case 179: char = '\u00B3'; break;
            case 180: char = '\u00B4'; break;

正解:

var stringVar = String.fromCharCode(intVar);
