Ubuntu – Chinese encoding in names of compressed files in zip

Sorry for asking a question similar to my previous one. The difference from the last question is that now it is in a zip archive where Chinese encoding in names of compressed files are not recognized, both after extraction and after listing the content of the zip archive:

$ unzip -l "严蔚敏数据结构(c语言版)教材及答案.zip"

  8444661                     11 files

I was wondering how to deal with this problem?

Thanks and regards!

update:

I have uploaded this zip archive to and it can be downloaded from http://www.mediafire.com/?dw87ee72m56evy9

I tried to use chardet to determine the encoding of the names of the compressed files by:

$ unzip -l "严蔚敏数据结构(c语言版)教材及答案.zip" | chardet
<stdin>: utf-8 (confidence: 0.99)

But are the file names indeed encoded in utf-8? Aren't they supposed to be in a foreign encoding? I guess the output by unzip -l are too much, and how shall I only single out the filenames in its output as input to chardet?
