not sur if it's the best solution but I add this function

https://github.com/Shopify/hydrogen/blob/2023-01/templates/demo-store/app/routes/%5Bsitemap.xml%5D.tsx

function htmlEncode(text: String) {
  text.replace(/[\u00A0-\u9999<>\&]/g, function(i) {
    return '&#'+i.charCodeAt(0)+';';
  });

  return '';
}

and

finalObject.image.title` = htmlEncode(product.title);

on line 75
