/**

* Protobuf-ES requires the Text Encoding API to convert UTF-8 from and to
|
|
* binary. This WHATWG API is widely available, but it is not part of the
|
|
* 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().
