Symptoms

From the existing bug - Bug 27966565 - Poor performance when using a combination of the unicode output, limit_page size

Problem Statement
=================
Customer is setting unicode output & limit_page size options in the code



{
VTDWORD dwordOption = SO_UNICODE;
DASetOption(hDoc, SCCOPT_EX_OUTPUTCHARACTERSET, &dwordOption,
sizeof(DWORD));
}

...
{
VTDWORD dwordOption = 1000000;
DASetOption((VTHDOC)0, SCCOPT_EX_PAGESIZE, &dwordOption,
sizeof(dwordOption));
}

This is causing the performance issue
