+Summary: GB2312 encoding BUG
+
+I have posted this BUG with earlier mono version before.
+Because Mono 0.30 include new ICU library, and I found BUG still exist. So
+I post it here again.
+I wrote this program:
+
+using System;
+using System.Text;
+using System.IO;
+                                                                          
+                                    
+public class MyApp
+{
+        public static void OutBytes(byte[] b, string name)
+        {
+                Console.WriteLine("Output bytes " + name);
+                for (int i = 0; i < b.Length; i++)
+                        Console.WriteLine("  " + name + "[{0}] = {1:X}", i,
+b[i]);
+        }
+                                                                          
+                                    
+        public static void Main()
+        {
+                Encoding e = Encoding.GetEncoding("gb2312");
+                byte[] b = new byte[] {0xC4, 0xE3, 0xBA, 0xC3};
+                                                                          
+                                    
+                string str = e.GetString(b);
+                byte[] b2 = e.GetBytes(str);
+
+                OutBytes(b, "b");
+                OutBytes(b2, "b2");
+        }
+}
+
+Bytes b is two chinese word in gb2312 encoding.
+The output of b and b2 should be the same.
+But it is not.
+I don't now which process is wrong, gb2312 to unicode or unicode to gb2312.
+It's a critical problem prevent chinese from using Mono.
