Same problem here...
While waiting for a fix, I wrote the following javascript to hide the issue. This might help some fellow Frenchmen.
$(document).ready(function() {
const targetNode = $("#emailVerificationControl");
const config = { attributes: true, childList: true, subtree: true };
const callback = function(mutationsList, observer) {
if(targetNode.html().includes("é")) {
var replaced = targetNode.html().replace(/é/g, 'é');
targetNode.html(replaced);
}
}
const observer = new MutationObserver(callback);
observer.observe(document.getElementById("emailVerificationControl"), config);
});
