Description Petru-Florin Mihancea 2017-06-23 07:53:45 UTC 
While experimenting with a CodeSonar plugin we develop, we noticed a
potential issue in file "main/sw/source/core/txtnode/txtedt.cxx" line 1815 function TransliterateText

Sequence <sal_Int32> aOffsets;
                String sChgd( rTrans.transliterate( GetTxt(), 
                        GetLang( nCurrentStart ), nCurrentStart, nLen, &aOffsets ));

                if (!m_Text.Equals( sChgd, nStt, nLen )) //Line 1815
                {
                    aChgData.nStart     = nCurrentStart;
                    aChgData.nLen       = nLen;
                    aChgData.sChanged   = sChgd;
                    aChgData.aOffsets   = aOffsets;
                    aChanges.push_back( aChgData );
                }

In line 1815 it might be possible that nCurrentStart must be used instead of nStt. 

Thanks,
