JavaScript object with Unicode property names in WASM

I have a JS promise returning an object with property names in Ukrainian. Trying to use := to convert it to Prolog dictionary works, but the names of properties become malformed.

For example, {елемент: “Стринг”} becomes {‘елеменÑ\u0082’:“Стринг”}.

A working example below. WASM-compiled swipl-bundle-devel.js should be placed in the same directory with the html file when running an http server.

<!DOCTYPE html>
<html>

<head>
  <meta charset="UTF8">
  <title>Unicode in := </title>
</head>

<body>

<script src="swipl-bundle-devel.js"></script>

<script charset="utf-8">

var swipl;

async function run_prolog()
{
  swipl = await SWIPL({arguments: ["-q"]})
  await swipl.prolog.load_scripts()
  await swipl.prolog.forEach("test.")
}

promise_unicode_dict = new Promise(resolve => {resolve({елемент: "Стринг"})})

run_prolog()

</script>


<script type="text/prolog" id="test.pl">

test :-
    Promise := promise_unicode_dict, await(Promise, Dict),
    writeln(Dict.елемент).

</script>

</body>
</html>

Thanks. Pushed a fix (commit 056cf002d02e325f1c2bf4841d0e848fd966e2a1). This affects JavaScript object property names and JavaScript class names that hold non-ASCII characters.
