I have a problem with files with a Unicode name in Zip. I am using vjslib.dll. in a normal scenario, it's working perfect but when I am trying to zip file which has a Unicode character name like "サンプルファイル.pdf"it's represented as a "???????.pdf", in zip file while extracting a zip file Unicode file name nane represent as a "_______.pdf" is there any way to generate a zip with the exact name of the file does not matter file name in English or another language

zipFileName = "c:\SampleZip\myfile.zip"

sourceFile

  1. c:\sample\サンプルファイル.pdf

  2. c:\sample\отличается.xml

    private void Zip(string zipFileName, string[] sourceFile)
{
    FileOutputStream filOpStrm = new FileOutputStream(zipFileName);
    ZipOutputStream zipOpStrm = new ZipOutputStream(filOpStrm);
    FileInputStream filIpStrm = null;

    foreach (string strFilName in sourceFile)
    {
        filIpStrm = new FileInputStream(strFilName);
        ZipEntry ze = new ZipEntry(Path.GetFileName(strFilName));
        zipOpStrm.putNextEntry(ze);
        sbyte[] buffer = new sbyte[1024];
        int len = 0;

        while ((len = filIpStrm.read(buffer)) >= 0)
        {
            zipOpStrm.write(buffer, 0, len);
        }
    }

    zipOpStrm.closeEntry();
    filIpStrm.close();
    zipOpStrm.close();
    filOpStrm.close();
}

  • First, it is bad practice to use `Close()` with your streams the way you did here. Wrap the streams with `using` statements instead (https://stackoverflow.com/questions/75401/what-are-the-uses-of-using-in-c-sharp). Second, i assume you use SharpZipLib. You should be able to enable Unicode support (more accurately UTF-8 support) for each ZipEntry individually by setting its `ZipEntry.IsUnicodeText` property to _true_. –  Sep 20 '18 at 15:08
  • vjslib.dll is old, being able to only use 8-bit encoding for names was an old .zip format restriction. Lots of shiny new zip libraries around. – Hans Passant Sep 20 '18 at 15:17
