[Qt-interest] Accented characters and QDom in Windows

[Ellen Kestrel]

Ah, good - how do I indicate encodings in the XML - is it specified with the
document type?  I have just been putting strings meant for humans to read
there, as the examples use things like "mydocument" and "MyML".  This is the
first time I've really played with XML, actually.

Reading XML:
  QDomDocument doc ("ConlangML");
  QFile file (filename + ".cdic");

  if (!file.open (QFile::ReadOnly))  {
    QMessageBox::warning (this, "", "Cannot read file.");
    return;
  }

  if (!doc.setContent (&file))  {
    QMessageBox::warning (this, "", "Cannot read XML.");
    file.close ();
    return;
  }

  file.close ();

Writing XML:
  QFile file (filename + ".cdic");
  QTextStream out (&file);

  if (!file.open (QFile::WriteOnly | QFile::Text))  {
    QMessageBox::warning (this, "", "Cannot write file.");
    return;
  }

  out << doc.toString ();

  file.close ();

Or is it to do with the QTextStream?
