Rated 4 out of 5 stars

I think this is excellent add-on if using single-byte code for file name.
I use Windows/Japanese-OS and usually use double-byte code file name. In this case, file name encode is changed from default(Shift-JIS) to UTF-8 during compression.
TrvTrv, Could you please solve this problem? Thanks in advance.

This review is for a previous version of the add-on (0.1.0). 

Hi Kuni and thanks for the review. Unfortunately, the character "issue" is due to zip library which is Mozilla API' one (see https://bugzilla.mozilla.org/show_bug.cgi?id=296795). As explained in tab #5 'character replacement' of settings dialog "Standard of zip format does not allow non-ASCII characters in name of compressed files". The character replacement feature is a way to solve the issue. I understand this should be a harsh nay impossible to achieve for non-ASCII alphabets, but this definitely cannot be overridden until the Mozilla API evolved.
