The following code (source is UTF-8):

factory.createTextAnnotation({
  // …
  contents: "Hello! こんにちは！ Привет!",
  // …
})

Produces following annotation:

Hello! Sfikao ˜@825B!

How to write UTF-8 strings to annotations correctly?

function stringToUtf16Raw(text) {
  let out = [];
  out.push(String.fromCharCode(254));
  out.push(String.fromCharCode(255));
  for (let c of text) {
    c = c.charCodeAt(0);
    out.push(String.fromCharCode(c >> 8));
    out.push(String.fromCharCode(c & 0xFF));
  }
  return out.join('');
}

factory.createTextAnnotation({
  // …
  contents: stringToUtf16Raw("Hello! こんにちは！ Привет!"),
  // …
})
