安装python对应库

 pip install chardet

检测文件编码

import chardet

# 检测文件编码
file_path = r'C:\Users\AA\Desktop\log.log' # 这里放文件和文件绝对路径
with open(file_path, 'rb') as f:
    raw_data = f.read(100000)  # 读取前10000个字节
    result = chardet.detect(raw_data)
    encoding = result['encoding']
    confidence = result['confidence']
    print(f"检测到的编码: {encoding}, 置信度: {confidence}")

使用检测到的编码读取文件

# 使用检测到的编码读取文件
detected_encoding = 'GB2312'  # 替换为检测到的编码
output_file_path = r'C:\Users\AA\Desktop\log_fixed.txt' # 这里写输出的文件的路径

try:
    with open(file_path, 'r', encoding=detected_encoding, errors='ignore') as f:
        text = f.readlines()

    with open(output_file_path, 'w', encoding='utf-8') as f:
        f.writelines(text)

    print("文件编码转换完成，已保存为 log_fixed.txt。")
except Exception as e:
    print(f"处理过程中出现错误: {e}")

用jupyter运行结果如下
