+Summary: DataTable.Select fails to match text with brackets
+
+Description of Problem:
+When using DataTable.Select to find rows with a text field containing
+brackets, no rows are returned.
+
+Steps to reproduce the problem:
+using System;
+using System.Data;
+
+// Compile with: mcs -r:System.Data DataSetTest2.cs
+
+public class DataSetTest2
+{
+	public static void Main()
+	{
+		DataSet set = new DataSet();
+		DataTable data = set.Tables.Add("MyTable");
+
+		data.Columns.Add(new DataColumn("Column1", Type.GetType("System.String")));
+
+		DataRow row = data.NewRow();
+		row["Column1"] = "(Test)";
+		data.Rows.Add(row);
+
+		row = data.NewRow();
+		row["Column1"] = "Test";
+		data.Rows.Add(row);
+
+		DataRow[] rows;
+		rows = data.Select("Column1 = 'Test'");
+		// This gives 1 row
+		Console.WriteLine("Rows containing 'Test': {0}", rows.Length);
+		// This gives 1 row under .NET and 0 rows under mono.
+		rows = data.Select("Column1 = '(Test)'");
+		Console.WriteLine("Rows containing '(Test)': {0}", rows.Length);
+	}
+}
+
+Actual Results:
+Rows containing 'Test': 1
+Rows containing '(Test)': 0
+
+Expected Results: (Observed when testing with MS .NET)
+Rows containing 'Test': 1
+Rows containing '(Test)': 1
+
+How often does this happen? 
+Always
+
+Additional Information:
+
+I am not sure exactly what circumstances cause the problem to occur.
