代码::

    import unicodedata

    # 示例字符串
    s1 = 'café'
    s2 = 'cafe\u0301'  # 已经是NFD形式
    s3 = '①②③'  # 包含兼容性字符

    # 使用NFKD规范化
    normalized_s1 = unicodedata.normalize('NFKD', s1)
    normalized_s2 = unicodedata.normalize('NFKD', s2)
    normalized_s3 = unicodedata.normalize('NFKD', s3)

    print(normalized_s1)  # 输出: cafe
    print(normalized_s2)  # 输出: cafe
    print(normalized_s3)  # 输出: 123

    # 比较规范化后的字符串
    print(normalized_s1 == normalized_s2)  # 输出: True
