Remove word microsoft only chars by unicode

I have to manage tousend from webpage on 4 language..
and i find many word microsoft special Chars to remove or replace...
on first steep i clean it from Tidy lib

tidiconfigfile.append("word-2000: yes");

after i find only one or two char wo Tidy can not remove
• . first is a tag <li> similar dot (unicode 8226) and second a real dot
but this html not having list i try it to remove on this way..

Code:

---

static inline QString HTML2Filter(  QString stream )
{
  QMap<uint,QString> webchars;
  webchars.insert(8226,QString(" ")); /* • */
  webchars.insert(194,QString(" "));
  webchars.insert(13,QString(""));
  webchars.insert(10,QString(""));
  QdocXhtml *convert = new QdocXhtml();
  QString html = convert->Format(stream);  /* tidy try to clean */
  for (int i = 0; i < html.size(); ++i)   {
 
            QChar sign = html.at(i);
            const uint asciiPos = (uint)sign.unicode();
            bool replaceUnis = false;
             if ((asciiPos >= 240) && (asciiPos <= 255)) {
               replaceUnis = true;
             } else if ((asciiPos >= 224) && (asciiPos <= 239)) {
               replaceUnis = true;
             } else if ((asciiPos >= 192) && (asciiPos <= 223)) {
               replaceUnis = true;
             } else if ( asciiPos >7999 ) {
               replaceUnis = true;
             }
                       if (replaceUnis) {
                       /////////QString charU = QString("%1").arg(asciiPos);
                       ///////QByteArray preU = QByteArray();
                       //////const int prepender = qBound(1,5 - charU.size(),5);
                       ///////preU.fill('0',prepender);
                       ///////const QString UnicodeChar = QString("&#%2%1").arg(charU).arg(preU.data());
                       const QString UnicodeChar = QString("&#%1").arg(asciiPos);
                       webchars.insert(asciiPos,UnicodeChar);
                       }
 
 
  }
   QMapIterator<uint,QString> i(webchars);
         while (i.hasNext()) {
             i.next();
             html = html.replace(QChar(i.key()),i.value());
          }
  return html;
}
