System.ArgumentException: Unrecognized character encoding

DiscUtils 0.11.0.2 Windows 10 64-bit .NET Framework 4.5.2

I only get this exception sometimes, and without any code or data changes.

            CDBuilder builder = new CDBuilder
            {
                UseJoliet = true,
                VolumeIdentifier = "XXXXXXXXXX"
            };

            foreach (KeyValuePair<string, string> file in files)
            {
                string sourceFilePath = file.Key;
                string destinationRelativeFilePath = file.Value;

                builder.AddFile(destinationRelativeFilePath, sourceFilePath);
            }
            builder.Build(isoFilePath);

Any ideas?

Thank you.

Seems like #77 - try the workaround there.

Although that is primarily for .NET Core, ... if it works, somethings wrong with .NET Framework (or you're secretly running Core :P) - if it doesn't, we need to figure out which Codepage it's trying to load.

I think the unsupported encoding type should be included in the exception message. https://github.com/DiscUtils/DiscUtils/blob/b89645ca99eedaf926fd2247c746c4528243d368/Library/DiscUtils.Iso9660/IsoUtilities.cs#L426

I'm not sure how the encoding could be anything other than BigEndianUnicode or ASCII.
