Problems with encoding when unzipping files

Velinkton · September 6, 2023, 12:36pm

Greetings

When I try to unzip a zip file using the “ExpandArchive” block, as a result, the encoding of the files gets lost. I tried using the “System.IO.Compression.ZipFile.ExtractToDirectory” function with the encoding in the parameter, but got the same result. I tried to unpack the archive with both Cyrillic and Latin characters - the result is always the same

How can I fix this?

I do the same, as you can see

github.com

open-rpa/openrpa/blob/master/OpenRPA.Utilities/Activities/ExpandArchive.cs

using System;
using System.Activities;
using OpenRPA.Interfaces;
using System.Activities.Presentation.PropertyEditing;
using System.Collections.Generic;
using System.ComponentModel;
using System.Diagnostics;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Runtime.InteropServices;
using Newtonsoft.Json;
using ExcelDataReader;
using System.Data;
using System.IO.Compression;

namespace OpenRPA.Utilities
{
    [Designer(typeof(ExpandArchiveDesigner), typeof(System.ComponentModel.Design.IDesigner))]
    [System.Drawing.ToolboxBitmap(typeof(ResFinder), "Resources.toolbox.expandarchive.png")]

This file has been truncated. show original

If you can easily test, maybe test if this solves the issue ?

Encoding.GetEncoding(850);

Unfortunately, it did not help me, although this time the characters are different

Try some more variations …
maybe this

SP866 encoding helped. I do not understand why other encodings containing Cyrillic characters could not process my file

Thank you very much!

Thank you for the feedback.
I will see if I can add an option to the two archive activities for setting this, but for now I’m glad you have a solution.
