如何将扩展拉丁字符更改为其非重音ASCII等效字符？

import unicodedata

def remove_accents(input_str):
    nfkd_form = unicodedata.normalize('NFKD', input_str)
    return u"".join([c for c in nfkd_form if not unicodedata.combining(c)])

input_str = "éàèü"
output_str = remove_accents(input_str)
print(output_str)

function removeAccents(str) {
  return str.normalize("NFD").replace(/[\u0300-\u036f]/g, "");
}

const inputStr = "éàèü";
const outputStr = removeAccents(inputStr);
console.log(outputStr);

import java.text.Normalizer;

public class RemoveAccents {
    public static String removeAccents(String inputStr) {
        return Normalizer.normalize(inputStr, Normalizer.Form.NFD)
                .replaceAll("\\p{InCombiningDiacriticalMarks}+", "");
    }

    public static void main(String[] args) {
        String inputStr = "éàèü";
        String outputStr = removeAccents(inputStr);
        System.out.println(outputStr);
    }
}
