如何在python中替换unicode dicts值并返回到unicode格式

# 原始Unicode字典
original_dict = {
    'name': u'张三',
    'age': u'30',
    'city': u'北京'
}

# 需要替换的值
replacement_dict = {
    u'张三': u'李四',
    u'北京': u'上海'
}

# 替换函数
def replace_unicode_values(original, replacements):
    new_dict = {}
    for key, value in original.items():
        if isinstance(value, str):  # 确保是字符串类型
            new_dict[key] = replacements.get(value, value)
        else:
            new_dict[key] = value
    return new_dict

# 执行替换
new_dict = replace_unicode_values(original_dict, replacement_dict)

print(new_dict)

{'name': '李四', 'age': '30', 'city': '上海'}

# 示例：确保字符串是UTF-8编码
value = value.encode('utf-8').decode('utf-8')
