Python UnicodeDecodeError: 'utf-8'不能解码字节0x81。

I am trying to use arelle to read a zip file of an XBRL filling.

我正在尝试使用arelle读取XBRL填充的zip文件。

This is done by giving the command:

这是通过发出以下命令来实现的:

C:\a>python arelleCmdLine.py -f C:\Python33\sec\2010\03\0000002809-0001047469-10
-002778-xbrl.zip

I am getting a UnicodeDecodeError

我得到一个UnicodeDecodeError

C:\a>python arelleCmdLine.py -f C:\Python33\sec\2010\03\0000002809-0001047469-10

It has do to something with utf-8 encoding and the character it represents but i cannot figure out what should i do. I found some guide but didn't help me address the issue.

它与utf-8编码和它所代表的字符有关，但我不知道该怎么做。我找到了一些指南，但没有帮助我解决这个问题。

The issue was created because the program demands to parse not the whole Zip folder but a specific file (in this case the instance folder) which lies in the subdirectory of the zip folder.

这个问题的产生是因为程序要求解析位于Zip文件夹的子目录中的特定文件(在本例中是实例文件夹)，而不是整个Zip文件夹。

To access the zip directory:

要访问zip目录:

If our file inside the zip directory is 1.xml
C:\a>python arelleCmdLine.py -f C:\Python33\sec\2010\03\0000002809-0001047469-10
-002778-xbrl.zip\1.xml

Verdict:

结论:

A UnicodeDecodeError: 'utf-8' cant decode byte 0x81 was caused because of the above reason.

一个UnicodeDecodeError: 'utf-8'不能解码字节0x81是由于上述原因造成的。

After a quick search up, the misbehaving byte appears to be the Ctrl key, according to the unicode byte database. As the appearance of Ctrl exists only as a haxi number and doesn't have it's own letter, I'm thinking that utf is having trouble printing it as a visible char, so the above error arises.

在快速搜索之后，根据unicode字节数据库，错误的字节似乎是Ctrl键。由于Ctrl的外观仅作为haxi数字存在，并且没有自己的字母，所以我认为utf无法将其打印为可见字符，因此会出现上面的错误。
