这个乱码 'ÉîÄϵç·' 是典型的 UTF-8编码被错误解码 导致的。下面提供多种恢复方法：
方法1：最常见的解决方案（UTF-8误解码为latin-1）

快速解决您的问题
针对您的具体情况 'ÉîÄϵç·'，直接使用：
garbled = 'ÉîÄϵç·'
fixed = garbled.encode('latin-1').decode('utf-8')
print(fixed) # 输出: 深南电路
预防措施
# 1. 存储时确保UTF-8编码
import json
def save_to_redis_properly(key, data):
"""正确保存数据到Redis"""
# 序列化为JSON（UTF-8）
