Remove accents in an array of strings

I have an array of strings, like so

let array = ['Enflure', 'Énorme', 'Zimbabwe', 'Éthiopie', 'Mongolie']

I want to sort it alphabetically, so I use array.sort(), and the result I get is :

['Enflure', 'Mongolie', 'Zimbabwe', 'Énorme', 'Éthiopie']

I guess the accents are the problems here, so I would like to replace the É with an E all over my array.

I tried this

for (var i = 0; i < (array.length); i++) {
    array[i].replace(/É/g, "E");
}

But it didn't work. How could I do this?
