Is there any library that can be used to decode Shift JIS text on Silverlight?

---

I was able to port Mono's implementation to .NET in less than an hour. This is the (minimal?) set of classes that needs to be ported (sorted by dependency):

1. I18N.Common.Strings
2. I18N.Common.MonoEncoding
3. I18N.CJK.CodeTable
4. I18N.CJK.DbcsConvert
5. I18N.CJK.DbcsEncoding
6. I18N.CJK.JISConvert
7. I18N.CJK.CP932

Additionally, the following file needs to be copied (loaded in the constructor of I18N.CJK.CodeTable):

• jis.table

The class that implements the "shift_jis" encoding is I18N.CJK.CP932. Note that it must be instantiated manually, not through Encoding.GetEncoding().

I found some info here:

This is the sample C# code from the link above (credits to Peter Bromberg). I cannot say for sure that it will work in Silverlight. I suppose it all depends on whether Encoding.GetEncoding("shift-jis") is available in SL:

public class FileConverter
{
    const int BufferSize = 8096;

    public static void Main(string[] args)
    {
        if (args.Length != 2)
        {
            Console.WriteLine 
                ("Usage: FileConverter <input file> <output file>");
            return;
        }
        //NOTE: you may need to use " Encoding enc = Encoding.GetEncoding("shift-jis"); " for non-standard code pages
        // Open a TextReader for the appropriate file
        using (TextReader input = new StreamReader 
               (new FileStream (args[0], FileMode.Open),
                Encoding.UTF8))
        {
            // Open a TextWriter for the appropriate file
            using (TextWriter output = new StreamWriter 
                   (new FileStream (args[1], FileMode.Create),
                    Encoding.Unicode))
            {

                // Create the buffer
                char[] buffer = new char[BufferSize];
                int len;

                // Repeatedly copy data until we've finished
                while ( (len = input.Read (buffer, 0, BufferSize)) > 0)
                {
                    output.Write (buffer, 0, len);
                }
            }
        }
    }
}
