在python中从xls读取unicode

我试图用Python读入一个.xls文件。该文件包含多个非ascii字符（即äöü）。我尝试了openpyxls和xlrd（我对xlrd寄予厚望，因为它应该以unicode读取所有内容），但两种方法都不起作用

我在尝试打印xls中的信息时，发现了许多关于编码/解码的答案，但我似乎都走不了那么远。仅在尝试读取文件后，此纸条就会出错：

import xlrd
workbook = xlrd.open_workbook('export_data.xls')

导致：

我在WindowsServer2008机器上的Python2.7上运行这个

根据我对OOo文档的阅读，xls使用了unicode的utf_16_le风格，而不是utf8（也就是说，它每个字符只使用两个字节存储在little endian中），因此请尝试：

有点晚了，但我希望您尝试过编码。

谢谢大家的反馈

我最终用编码覆盖函数修复了它。我无法找到cp代码对应于德语字符的Microsoft文档，所以我尝试了所有这些代码。最终我找到了cp1251，它成功了

workbook = xlrd.open_workbook(path, encoding_override="cp1251")

workbook = xlrd.open_workbook(path, encoding_override="cp1251")
