Move TextEncoder out of lib.dom.d.ts.

TextEncoder

Suggestion

Put (window|global).TextEncoder in a library that is automatically available to both browser and nodejs.

Use Cases

TextEncoder now exists on window in all major browsers as well as on global in NodeJS (as of NodeJS 11). At the moment, the TextEncoder definition lives in lib.dom.d.ts which means it isn't available when working on a project/library that is targeting both NodeJS and Browser.

I don't mind submitting a PR, but I don't know where the appropriate location for such a change is, and how to reconcile it properly with removal from lib.dom.d.ts. It isn't part of an annual ES specification, but it should go somewhere that is automatically included in both browser and node now that it is implemented by both. The specification for it can be found at https://encoding.spec.whatwg.org/ and I believe that is what has been implemented in NodeJS.

Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

Inizia leggendo lib.dom.d.ts e confrontando la disponibilità di TextEncoder descritta per i browser e NodeJS. Il lavoro è completato quando la dichiarazione viene rimossa da lib.dom.d.ts e inserita in una libreria automaticamente disponibile per i progetti browser e NodeJS; l'issue non indica alcun file di test.
