 * Protobuf-ES requires the Text Encoding API to convert UTF-8 from and to

 * ECMAScript standard. On runtimes where it is not available, use this
 * function to provide your own implementation.
 *
 * Note that the Text Encoding API does not provide a way to validate UTF-8.
 * Our implementation falls back to use encodeURIComponent().
