Comment 15 for bug 1422290

> Did upstream say anything?

I've got a reply from a developer of unzip, but he is also not familiar with those charset issues. I need to discuss it more in upstream. However what I'm trying to do here is a relatively short-term solution. I believe the request in the attached branch is still valid as downstream to workaround real-life problem which users are seeing in daily-use (as non-latin charset users).

I took the charset list from:
https://msdn.microsoft.com/en-us/goglobal/bb964654
and
msdos/msdos.c in unzip package:
   1682 case 932: /* Japanese */
   1683 case 949: /* Korean */
   1684 case 936: /* Chinese, simple */
   1685 case 950: /* Chinese, traditional */
   1686 case 874: /* Thai */
   1687 case 1258: /* Vietnamese */

I'm not so familiar with Chinese charset. I thought CP936 was suitable because we were trying to solve the issue with localized Windows made zip files. GBK may have wider coverage than CP936 though.
