Comment 12 for bug 1422290

I have sent an enhancement request to upstream through http://www.info-zip.org/zip-bug.html since the issue is still reproducible with 6.1c19-BETA which you can try from: https://launchpad.net/~nobuto/+archive/ubuntu/build-test/+build/7630500

Putting a copy of the request here for your reference.

====

This is an enhancement request. Thanks to ICONV_MAPPING(-O/-I options), we can specify character encoding when extracting zip files. However in combination with GUI application(e.g. file-roller on Linux), there is no way to specify -I/-O from a user perspective. Therefore We cannot extract zip files created on localized Windows system properly with GUI.

A workaround would be exporting UNZIP and ZIPINFO variables with "-O <local charset on Windows>" per locale on login by putting [1] under /etc/profile.d/.

It would be nice if unzip had fallback charset mapping per locale out of the box. I have created a test case to handle 3 types of zip files in ja_JP locale.

(without [1], 3rd test case, fat and CP932, will fail.)
