'gbk' codec can't decode byte 0x99 in position 1148729: illegal multibyte sequence

这个错误是由于Python的open方法默认编码取决于平台，如果是Windows平台，默认编码是gbk，而如果文件是utf-8编码，就会报这个错误。解决办法是在打开文件的代码中指定编码方式为utf-8，例如：txtfile = open('testdata1.txt', 'r', encoding='utf-8')。这样就可以正确读取文件内容了。\[1\]

至于你提到的'gbk' codec can't decode byte 0x99 in position 1148729: illegal multibyte sequence错误，这个错误是由于在读取文件时遇到了非法的多字节序列。可能是文件中包含了无法被gbk编码解析的字符。解决办法是使用正确的编码方式打开文件，例如utf-8。你可以尝试使用相同的方法来解决这个问题。\[2\]
