symbian字元編碼

1 uint8,gbk,unicode,utf-8之間的轉換:
TUint8 dataGbk[4]   = {0xBA ,0xBA ,0xD7 ,0xD6};
TUint8 dataUnicode[4] = {0x49 ,0x6C ,0x57 ,0x5B};
TUint8 dataUtf8[6]   = {0xE6 ,0xB1 ,0x89 ,0xE5 ,0xAD ,0x97};

//直接
HBufC8* strGbk8 = HBufC8::NewL(4);
strGbk8->Des().Append(dataGbk,4);
DEBUGLOG( iFileLogger,*strGbk8);
delete strGbk8;

HBufC8* strUnicode8 = HBufC8::NewL(4);
strUnicode8->Des().Append(dataUnicode,4);
DEBUGLOG( iFileLogger,*strUnicode8);
delete strUnicode8;

HBufC8* strUtf8 = HBufC8::NewL(6);
strUtf8->Des().Append(dataUtf8,6);
DEBUGLOG( iFileLogger,*strUtf8);

//utf8轉unicode
HBufC16* strUtf16 = HBufC16::NewLC(2);
CnvUtfConverter* Converter = new (ELeave) CnvUtfConverter();
TPtr ptr = strUtf16->Des();
Converter->ConvertToUnicodeFromUtf8(ptr, *strUtf8);
delete Converter;
DEBUGLOG( iFileLogger,*strUtf16);
CleanupStack::PopAndDestroy(strUtf16);

delete strUtf8;

TUint16 dataGbk16[2]   = {0xBABA ,0xD6D7};
TUint16 dataUnicode16[2]  = {0x6C49 ,0x5B57};

//直接顯示
HBufC16* strGbk16 = HBufC16::NewL(2);
strGbk16->Des().Append(dataGbk16,2);
DEBUGLOG( iFileLogger,*strGbk16);
delete strGbk16;

//unicode轉換成GBK
HBufC16* strUnicode16 = HBufC16::NewLC(2);
strUnicode16->Des().Append(dataUnicode16,2);
CCnvCharacterSetConverter* converter = CCnvCharacterSetConverter::NewLC();
if (converter->PrepareToConvertToOrFromL(KCharacterSetIdentifierGbk,
CEikonEnv::Static()->FsSession()) == CCnvCharacterSetConverter::EAvailable)
{
HBufC8* ret = HBufC8::NewLC(2);
TPtr8 ptr8 = ret->Des();
converter->ConvertFromUnicode(ptr8, *strUnicode16);
DEBUGLOG( iFileLogger,*ret);
CleanupStack::PopAndDestroy();
}
CleanupStack::PopAndDestroy(2);

2 儲存檔案,儲存成GBK的才能正常開啟看.

3 顯示在螢幕上,unicode編碼的才能正常顯示
    TUint16 dataGbk16[2]       = {0xBABA ,0xD6D7};
    TUint16 dataUnicode16[2]  = {0x6C49 ,0x5B57};
   
    //直接顯示
    HBufC16* strGbk16 = HBufC16::NewL(2);
    strGbk16->Des().Append(dataGbk16,2);   
    gc.DrawText(*strGbk16,TPoint(10,30));
    delete strGbk16;

第一個不能正常顯示.
第二個顯示"漢字"
