Indeed the error was caused because of the byte order mark, although
the Unicode standard recommends against the BOM for UTF-8 but many
Windows programs (Notepad, Visual C++ etc) add the bytes 0xEF, 0xBB,
0xBF at the start of any document saved as UTF-8, which in turn get
 to the start of the MathML causing the gtkmathview to fail.

I'll revert the earlier commit and identify the BOM as such with
something like :

while (pStream->getChar(c))
        {
                // Ignore BOM
                if(c!= ((UT_UCSChar)0xEF) && c!=((UT_UCSChar)0xBB) && c!=((UT_UCSChar)0xBF))
                {
                        uc = static_cast<unsigned char>(c);
                        BB.append(&uc,1);
                }
        }
