	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 "ü"
	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 ).
