Which charset are you using? Can you send a TDSDUMP output ?

Hi @freddy77

please find the below details

Error: retVal.size() was not equal to binLongVarCharMaxStr.size(); retVal.size()-->1; binLongVarCharMaxStr.size()-->5461 odbc_util.c:214: odbc_wide2utf: Assertion `p+1-out <= o_len' failed. make: * [Makefile:293: test] Aborted (core dumped**)

Suspecting Method: SQLPrepareW()

currently we are using char

    if defined (__linux)
        //nchar_char = 0xc290;
        nchar_char = 0xC290;
        nchar_hex = L"C290";
    #else
        nchar_char = 0x90c2;
    nchar_hex = L"90c2";

ConvertBetweenCodePages: const char dstCodePage [] = "UCS-2", // Destination Code Page. srcCodePage [] = "WCHAR_T"; // Source Code Page
