Public bug reported:
unzip 6.0-21ubuntu1.1
Linux Mint 19.3 (Ubuntu 18.04)
ZIP files doesn't store information about character set used to encode
filenames in the archive. In the case that user tries to extract ZIP
file created at Windows with unzip at Linux, filenames can be corrupted
in the case those contain characters from extended ASCII table...
unzip can handle this, it has switches "-I" and "-O" to specify encoding
of filenames in the archive.
$ unzip -h | grep CHARSET
-O CHARSET specify a character encoding for DOS, Windows and OS/2 archives
-I CHARSET specify a character encoding for UNIX and other archives
Information about these switches is missing in manual page (man unzip)
This is a way how to "list" files in ZIP file from Czech edition of
Windows at Ubuntu:
$ unzip -l -O CP852 archive-win.zip
File archive-win.zip is in format 2.0
Other problem is that it is not possible to instruct ZIP to create ZIP
archive with specific encoding; so I cannot create at Linux ZIP file
that has file names encoded in CP852 codepage, such archive could be
opened at Czech Windows without issue...
Another problem is that it is not possible to create ZIP file in older
format, like 2.0 (zip creates archives in format 3.0 (it seems it could
be a problem for Windows user because that file uses UTF-8 characters).
I am not sure what is problem here but there is a problem... I need a
computer with Windows to check details.
