unzip missing code pages

[Ľubomír Mlích]

Bug 580961 was solved, but nobody created another bug to repair encoding as is described in comments bellow.

Testcase: Archive file with name encoded in CP-1250 and then unzip it. I have 12.04 and package unzip (6.0-4ubuntu2) installed.

I think revision will be better than waiting for people to ask for repairing their specific encoding.

Thanks.

Status changed to 'Confirmed' because the bug affects multiple users.

I'm using this script to work around the bug:
http://bazaar.launchpad.net/~ts.sch.gr/sch-scripts/trunk/view/head:/sch-scripts/unzip

Click on "Download file", then run
sudo mv unzip /usr/local/bin/unzip
sudo chmod +x /usr/local/bin/unzip

Then edit the file:
sudo gedit /usr/local/bin/unzip

Find the line that says:
    el) charset=cp737 ;;

...and either on top of it, or under it, add a similar line for your LANG <=> DOS codepage mapping.

Maybe when we have several mappings, someone will take the time to reimplement it inside unzip.c so that we don't have to use a wrapper anymore.

Thanks, nice script.

My line looks like this:

    cs) charset=cp852;;

If You give me three more missing code pages, I'll try contact unzip maintainers and ask them for fix.

For help on codepages, look at: http://en.wikipedia.org/wiki/Code_page

Thank you for reporting this bug.

Ubuntu 12.04 (precise) reached end-of-life on April 28, 2017.

See this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

I tetsted on 22.04 (Jammy Jellyfish) if the bug still exists, but it seems to be fixed at some point.

Testcase:
1. create test file:
echo "Hello World!" > '~€…†‡‰Š‹ŚŤŽŹ•–—™š›śťžźNPˇ˘Ł¤Ą¦§¨©Ş«¬®Ż°±˛ł´µ¶·¸ąş»Ľ˝ľżŔÁÂĂÄĹĆÇČÉĘËĚÍÎĎĐŃŇÓÔŐÖ×ŘŮÚŰÜÝŢßŕáâăäĺćçčéęëěíîďđńňóôőö÷řůúűüýţ˙.txt'
2. force filename encoding:
convmv -f utf8 -t cp1250 '~€…†‡‰Š‹ŚŤŽŹ•–—™š›śťžźNPˇ˘Ł¤Ą¦§¨©Ş«¬®Ż°±˛ł´µ¶·¸ąş»Ľ˝ľżŔÁÂĂÄĹĆÇČÉĘËĚÍÎĎĐŃŇÓÔŐÖ×ŘŮÚŰÜÝŢßŕáâăäĺćçčéęëěíîďđńňóôőö÷řůúűüýţ˙.txt'
3. create zip file:
zip test.zip '~€…†‡‰Š‹ŚŤŽŹ•–—™š›śťžźNPˇ˘Ł¤Ą¦§¨©Ş«¬®Ż°±˛ł´µ¶·¸ąş»Ľ˝ľżŔÁÂĂÄĹĆÇČÉĘËĚÍÎĎĐŃŇÓÔŐÖ×ŘŮÚŰÜÝŢßŕáâăäĺćçčéęëěíîďđńňóôőö÷řůúűüýţ˙.txt'
4. unzip file:
unzip -d extracted test.zip
5. check if there are decoding errors:
ls -la extracted/

We appreciate that this bug may be old and you might not be interested in discussing it any more. But if you are then please upgrade to the latest Ubuntu version and re-test. If you then find the bug is still present in the newer Ubuntu version, please add a comment here telling us which new version it is in.

Hello,
I've checked in Ubuntu 23.04 and seems this works well, my steps:

$ touch šč.txt
$ zip test2.zip šč.txt
$ unzip test2.zip -d extracted2
$ ls -la extracted2
drwxrwxr-x 2 myusername mygroup 4096 čen 9 21:14 .
drwxrwxr-x 4 myusername mygroup 4096 čen 9 21:14 ..
-rw-rw-r-- 1 myusername mygroup 0 čen 9 21:13 šč.txt

seems solved to me.

[Ľubomír Mlích (lubomir-mlich)]
