+      Description : CT-GCF[34.2.5.1] - MS fails to display class 0 MT SMS when it contains alphanumeric and special characters
+      
+	Nov 24, 2006 DR: OMAPS00092906 - x0039928
+    	Description: CT-GCF[34.3]-Some broadcasted charcters not dispayed correctly in MMI
+    	Solution: g_translation_8bit_table[] array is modified. Changed code 0xFF to 0x1B.
+    
+    Jun 09, 2006 DR: OMAPS00080543 - xreddymn
+    ATB_convert_String does not work correctly for 7-bit GSM to 8-bit
+    conversion. This is due to a dependency with ACI function. This has been
+    replaced now with an independent conversion function, which 
+    ATB_convert_String can call.
+
+	Mar 30, 2005	REF: CRR 29986	xpradipg
+	Description: Optimisation 1: Removal of unused variables and dynamically
+	allocate/ deallocate mbndata
+	Solution: removed the definition of translation_ascii_2_unicode and added 
+	the extern declaration
+
+       March 24, 2005 REF: CRR MMI-FIX-9828 x0012852
+	Description: BMI having problems with Umlauts ,especially "?
+	Solution: g_translation_8bit_table[] array is modified . Changed codes 0x80 , 0x81,      
+                     0x82 to ox81, 0x82 ,0x83 respectively.
+
+	Jan 05, 2005 REF: CRR MMI-FIX-24757 xnkulkar
+	Description: the display doesn´t show special chars correctly; if there is an "@" in the text, the "@" and 
+			    text after is not visible
+	Solution: Fix for MMI-SPR-25978 has solved the problem of data loss after '@' symbol. However, some other 
+	              symbols (like ?etc.) were not displayed properly. Modified the g_translation_8bit_table[] array 
+			to take care of all the special GSM character set .
+ 
+	Nov 30, 2004 REF: CRR MMI-SPR-25978 xnkulkar
+	Description: Messages:Not able to receive message after @ in the receiver phone (Bug raised in 3.x)
+	Solution: in g_translation_8bit_table, the value for '@' symbol was used as 0x00. It has been
+	              changed to 0x40 now.
+ 	
+ 	26-05-04      CRR 19656    Sandip and Deepa M.D
+      	Fix for The Dsample doesn't display lines ( <CR> or <LF> ) in the SETUP IDLE 
+	TEXT command.
+	Fix for The idle screen is empty when a SETUP IDLE TEXT command is sent with 
+	a long text ( 239 characters ).
