python charmap 编解码器无法将位置 Y 字符映射中的字节 X 解码为 <undefined>
python charmap codec can't decode byte X in position Y character maps to <undefined>
我正在试验 python 库进行数据分析，我面临的问题是这个异常
UnicodeDecodeError was unhandled by user code Message: 'charmap' codec
can't decode byte 0x81 in position 165: character maps to < undefined>
我已经调查了类似问题的答案，OP 似乎正在阅读或打印不同编码的文本。
在我的代码中，错误出现在导入语句中，这让我很困惑。
我在 Visual Studio 2015 上使用 python 64 位 3.3
geotext 是显示错误的库。
请指出在哪里可以处理此错误。
这是我解决这个问题的方法（适用于geotext 0.3.0）
