Just to make sure, it was about the content of the member, rather
than the file name of the member, right?
In regard to the content of file, I thought I addressed the problem,
but I hadn't done anything with Monticello yet...
In regard to the file name it is a bit trickier. Since there are
tons of different Zip files around with member names that contains 8
bit (not 7 bit characters), and its interpretation is based on the
local encodings. Japanese version of Windows XP creates .zip files
whose member name encoding is Shift-JIS and my guess is that European
version of Windows do it with Latin-1.
The half-based solution was to use the platform-default encoder to
create the byte-representation of wide strings, but I have been
wanting to add extra attribute to the zip archieve to tell the file
member name encoding. Ned told me how to do it, but I haven't got
around to do it...
