Transform HTML entities to unicode

The Babel JSX compiler converts HTML entities into the unicode characters they represent. In ReScript, we have to use the actual unicode directly. For some characters, like   this isn't always convenient.

Would it be possible for the React PPX to do the same transformation that Babel does? See their entity map for reference: https://github.com/babel/babel/blob/b3e2bcda73dea7d68b4c82bfabb92acb11b1ed90/packages/babel-parser/src/plugins/jsx/xhtml.js

Babel example

Input

let f = () => <div>&nbsp;</div>;

output

let f = () => /*#__PURE__*/React.createElement("div", null, "\xA0");

ReScript example

Input

let f = () => <div> {React.string("&nbsp;")} </div>

Output

function f(param) {
  return React.createElement("div", undefined, " ");
}

Note that "  will render as-is, not as an actual nonbreaking space character.

Inizia con la trasformazione JSX di React PPX e confrontane il comportamento con la mappa delle entità JSX collegata di Babel. Usa gli esempi di Babel e ReScript nell’issue come casi da verificare; il lavoro è completato quando le entità HTML supportate producono i caratteri Unicode corrispondenti, come fa Babel.
