Chinese chars - Using lib to zip and unzip strings with comments

Hi all,

 I'm using the following code to zip and unzip strings and set the comments into memory.

 All works, except if I have chinese chars. Can you help me out? (At this time the comments are being returned as ???? )

             /// <summary>

            /// Zips the content.

            /// </summary>

            /// <param name="entryName">Name of the entry.</param>

            /// <param name="body">The body.</param>

            /// <param name="comment">The comment.</param>

            /// <returns></returns>

            public static string Zip(string entryName, string body, string comment)

            {

                MemoryStream outputMemStream = new MemoryStream();

                ZipOutputStream zipStream = new ZipOutputStream(outputMemStream);

                ZipEntry newEntry = new ZipEntry(entryName);

                newEntry.IsUnicodeText = true;

                newEntry.DateTime = DateTime.Now;

                zipStream.PutNextEntry(newEntry);

                StreamUtils.Copy(Utilities.GenerateStreamFromString(body), zipStream, new byte[4096]);

                zipStream.SetComment(comment);

                zipStream.SetLevel(3);

                zipStream.CloseEntry();

                zipStream.IsStreamOwner = false;

                zipStream.Close();

                outputMemStream.Position = 0;

                return Convert.ToBase64String(outputMemStream.ToArray());

            }

            /// <summary>

            /// Unzips the specified content.

            /// </summary>

            /// <param name="contentBase64">The content.</param>

            /// <param name="entryName">Name of the entry.</param>

            /// <param name="body">The body.</param>

            /// <param name="comment">The comment.</param>

            public static void Unzip(string contentBase64, out string entryName, out string body, out string comment)

            {

                Stream inStream = new MemoryStream(Convert.FromBase64String(contentBase64));

                MemoryStream outputMemStream = new MemoryStream();

                ZipOutputStream zipOut = new ZipOutputStream(outputMemStream);

                zipOut.IsStreamOwner = false;

                zipOut.SetLevel(3);

                ZipFile zipFile = new ZipFile(inStream);

                zipFile.IsStreamOwner = false;

                comment = zipFile.ZipFileComment;

                ZipEntry zipEntry = zipFile[0];

                entryName = zipEntry.Name;

                Stream zipStream = zipFile.GetInputStream(zipEntry);

                body = Utilities.GenerateStringFromStream(zipStream);

                zipOut.Close();

            }
