初步判断是字节数据 -\x80 W -\x9eX\xcb@—P\xcd\xf2\xf0[E 这段数据\x80 导致的问题

测试用的代码:

file_path = "errors/113_gbk.txt"
line = True
count = 0
with open(file_path, "rb") as f:
    while line:
        try:
            rl = f.readline()
            #line = rl.decode("gb18030", errors="ignore")
            count +=1
            if count == 181:
                import pdb;pdb.set_trace()
                print(rl)
        except Exception as e:
            print(e)

本文档在chrome浏览器中表现也是如此

利用PyIcu可以通过GBK编码格式解码出正确内容，但GB18030会报错
