What do you use to check the result ? Windows 7's explorer ?

JSZip uses UTF8 to encode/decode the file name inside a zip file (see also #211 for other encodings).
Unfortunately, the compressed folders feature on Windows (up to and including Windows 7) uses the locale of the machine which will open the file (even with an unicode flag). Other file archivers that handle UTF8 will be fine (I just tested your example on my machine).
If you use #211 to use a different encoding for the file name, you might have issues with other tools like 7zip which only understand UTF8.
This issue is not specific to JSZip, others have this issue too (1, 2, 3).

We need to add this in the documentation, this question is asked regularly.
