29 May 7, 2007 OMAPS00130278 a0393213(R.Prabakar)
30 Description : CT-GCF[34.2.5.1] - MS fails to display class 0 MT SMS when it contains alphanumeric and special characters
31
32 Nov 24, 2006 DR: OMAPS00092906 - x0039928
33 Description: CT-GCF[34.3]-Some broadcasted charcters not dispayed correctly in MMI
34 Solution: g_translation_8bit_table[] array is modified. Changed code 0xFF to 0x1B.
35
36 Jun 09, 2006 DR: OMAPS00080543 - xreddymn
37 ATB_convert_String does not work correctly for 7-bit GSM to 8-bit
38 conversion. This is due to a dependency with ACI function. This has been
39 replaced now with an independent conversion function, which
40 ATB_convert_String can call.
41
42 Mar 30, 2005 REF: CRR 29986 xpradipg
43 Description: Optimisation 1: Removal of unused variables and dynamically
44 allocate/ deallocate mbndata
45 Solution: removed the definition of translation_ascii_2_unicode and added
46 the extern declaration
47
48 March 24, 2005 REF: CRR MMI-FIX-9828 x0012852
49 Description: BMI having problems with Umlauts ,especially "?
50 Solution: g_translation_8bit_table[] array is modified . Changed codes 0x80 , 0x81,
51 0x82 to ox81, 0x82 ,0x83 respectively.
52
53 Jan 05, 2005 REF: CRR MMI-FIX-24757 xnkulkar
54 Description: the display doesn´t show special chars correctly; if there is an "@" in the text, the "@" and
55 text after is not visible
56 Solution: Fix for MMI-SPR-25978 has solved the problem of data loss after '@' symbol. However, some other
57 symbols (like ?etc.) were not displayed properly. Modified the g_translation_8bit_table[] array
58 to take care of all the special GSM character set .
59
60 Nov 30, 2004 REF: CRR MMI-SPR-25978 xnkulkar
61 Description: Messages:Not able to receive message after @ in the receiver phone (Bug raised in 3.x)
62 Solution: in g_translation_8bit_table, the value for '@' symbol was used as 0x00. It has been
63 changed to 0x40 now.
64
65 26-05-04 CRR 19656 Sandip and Deepa M.D
66 Fix for The Dsample doesn't display lines ( <CR> or <LF> ) in the SETUP IDLE
67 TEXT command.
68 Fix for The idle screen is empty when a SETUP IDLE TEXT command is sent with
69 a long text ( 239 characters ).
