Question

I would like to convert a QString containing Unicode characters to plain HTML text. For instance “私” would become “私”.

Is there such a functionality in Qt? I found the function QString Qt::escape ( const QString & plain ) but it only converts HTML metacharacters <, >, &, and “.

There seems to be a lot of Qt classes and functions for encoding and internationalization but I just don’t know where to look at.

I asked in Qt Centre forums and someone gave me the answer I needed. Here it is.

Here is the code that was suggested and that solved my problem:

QString ampersand_encode(const QString &string) {
  QString encoded;
  for(int i=0;i<string.size();++i) {
    QChar ch = string.at(i);
    if(ch.unicode() > 255)
      encoded += QString("&#%1;").arg((int)ch.unicode());
    else
      encoded += ch;
  }
  return encoded;
}
