var str = "bôn";
var charset = "not_used";

// Unicode escape all chars using \uHHHH
success = sb.SetString(str);
sb.Encode("unicode-escape-all",charset);
console.log(sb.GetAsString());
// Output is \u0062\u00f4\u006e

// Unicode escape only 8bit chars using \uHHHH
success = sb.SetString(str);
sb.Encode("unicode-escape-8bit",charset);
console.log(sb.GetAsString());
// Output is b\u00f4n

// To use uppercase hex chars (A-F), add "-upper" to the encoding name
