Re: [tlug] Bogus Japanese zipfiles [was: Kudos to Jim Breen]

Speaking of Gentoo, its version of "unzip" comes with an optional "natspec" patch, which just works.

$ unzip --help | grep CHAR

  -O CHARSET  specify a character encoding for DOS, Windows and OS/2 archives

  -I CHARSET  specify a character encoding for UNIX and other archives

The meaning of "-O" and "-I" is a bit of a mystery, but it one doesn't work, try the other.

E.g., take this file: https://github.com/Stuk/jszip/files/654150/jpnfile.zip

It's one of the problematic ones:

$ unzip -l jpnfile.zip 

Archive:  jpnfile.zip

  Length      Date    Time    Name

---------  ---------- -----   ----

        0  12-15-2016 16:32   jpnfile/index.html

        0  12-15-2016 16:32   jpnfile/ÉVé╡éóâeâLâXâg âhâLâàâüâôâg.txt

---------                     -------

        0                     2 files

So use "-O" to try a different encoding:

$ unzip -O sjis -l jpnfile.zip 

Archive:  jpnfile.zip

  Length      Date    Time    Name

---------  ---------- -----   ----

        0  12-15-2016 16:32   jpnfile/index.html

        0  12-15-2016 16:32   jpnfile/新しいテキスト ドキュメント.txt

---------                     -------

        0                     2 files

LoL, after many years of occasional need to wrestle those, I published this:

https://github.com/thinrope/gentoo-nifty-scripts/blob/master/usr/local/bin/jzip

(although it is somewhat Gentoo-related (paths), the script is mostly
standalone)

I think patching upstream (zip, p7zip) is still better, but haven't
had urge to do it.


Cheers,
