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.

React PPX JSX変換から始め、BabelのリンクされたJSXエンティティマップと動作を比較します。Issue内のBabelとReScriptの例を確認するケースとして使い、Babelと同様に、サポートされているHTMLエンティティが対応するUnicode文字を生成すれば完了です。
