+Bug#: 77646
+Product: Mono: Class Libraries
+Version: 1.1
+OS Details: 
+Status: NEW   
+Priority: Normal
+Component: CORLIB
+AssignedTo: mono-bugs at ximian.com

+TargetMilestone: ---
+Summary: [2.0] Char.GetUnicodeCategory returns wrong value for \u0be6
+In both 1.0 and 2.0 profile, Mono's Char.GetUnicodeCategory returns 
+UnicodeCategory.OtherNotAssigned for \u0be6.
+However in the 2.0 profile it should return 
+UnicodeCategory.DecimalDigitNumber (to match MS.NET 2.0).
+Since the UnicodeCategory is, amongst other things, used to determine 
+whether a given character is a digit, this issue will cause Char.IsDigit 
+and Char.IsLetterOrDigit to return incorrect results too.
+This bug results in a test failure in CharCategoryTest.IsDigit on MS.NET 
+To reproduce, compile and run the following code snippet (using mcs and 
+using System;
+public class Test {
+  static void Main () {
+    Console.WriteLine (char.GetUnicodeCategory ('\u0be6'));
+  }
+Actual result:
+OtherNotAssigned (on both 1.0 and 2.0 profile)
+Expected result:
+OtherNotAssigned (on 1.0 profile)
+DecimalDigitNumber (on 2.0 profile)
