Yes i fount this function
Now i am in this function:
I mark line in red when i finished this line i got
the sSrc become empty however rString is not empty:
m_pHeapBuffer 0x11bb5fc8 "TEXTTEXTTEXTTEXTTEXTTEXTTEXTTEXTTEXTTEXTTEXTTEXT"
PdfString PdfSimpleEncoding::ConvertToEncoding( const PdfString & rString,
const PdfFont* ) const
{
if( !m_pEncodingTable )
const_cast<PdfSimpleEncoding*>(this)->InitEncodingTable();
PdfString sSrc = rString.ToUnicode(); // make sure the string is unicode
and not PdfDocEncoding!
pdf_long lLen = sSrc.GetCharacterLength();
if( !lLen )
return PdfString("");
char* pDest = static_cast<char*>(malloc( sizeof(char) * (lLen + 1) ));
if( !pDest )
{
PODOFO_RAISE_ERROR( ePdfError_OutOfMemory );
}
const pdf_utf16be* pszUtf16 = sSrc.GetUnicode();
char* pCur = pDest;
for( int i=0;i<lLen;i++ )
{
pdf_utf16be val = pszUtf16[i];
#ifdef PODOFO_IS_LITTLE_ENDIAN
val = ((val & 0xff00) >> 8) | ((val & 0xff) << 8);
#endif // PODOFO_IS_LITTLE_ENDIAN
*pCur = m_pEncodingTable[val];
if( *pCur ) // ignore 0 characters, as they cannot be converted to the
current encoding
++pCur;
}
*pCur = '\0';
PdfString sDest( pDest ); // fake a PdfDocEncoding string .... would be
more clear if we return a buffer
free( pDest );
return sDest;
}
when i return from this function the sDest m_pHeapBuffer is 0x00000000 <Bad
Ptr> char *
