Encoding 437 data could not be found while unzipping in Android 10
While trying to unzip an archive with ICSharpCode.SharpZipLib.Zip.ZipFile in Android 10. This code:
using (zf = new ZipFile(fsInput)){ .... }
give me the error:
Encoding 437 data could not be found. Make sure you have correct international codeset assembly installed and enabled.

I tried to copy all I18N.*.dll from Editor's dll folder to plugins folder. But the error is still there. Any help is welcome. Fabio
Hello from months later,
I had same issue while using NPOI. Just managed to overcome this problem.
TLDR: Modify "ZipConstants.DefaultCodePage" value in SharpZipLib to UTF8 or encoding related to your setup. (Before using NPOI/SharpZipLib)
ICSharpCode.SharpZipLib.Zip.ZipConstants.DefaultCodePage = System.Text.Encoding.UTF8.CodePage;
I had no problem when i use .xlsx write operations on Unity Editor. However, testing project on build was giving same error with 857 encoding code (turkish-utf8 iso format). I looked up source code of sharpziplib and github issues of sharpziplib, i found this issue and problem was related to ZipConstants takes ZipConstants:15 -> private static int defaultCodePage = Thread.CurrentThread.CurrentCulture.TextInfo.OEMCodePage; (OEMPage info) which gives unexpected errors on default usage. In Xamarin forum, many people pointed this problem as non-sharplibzip problems but encoding errors and their solution was setting project encoding to utf-8. In Unity, we cannot do that. So, forcing ZipConstants.defaultCodePage or using custom code page for write-read operations solves the problem.
Hi, can you please explain more ? or any example?
