QT关于中文字符串长度问题

[jxnuwzq]

   string s;
   while(s!="#")
  {
        cout<<"Please input a chinese sentence:";
        cin>>s;
        sentence=QString::fromStdString(s).toLocal8Bit();
        qDebug()<<sentence.size();
   }

RT，但是中文长度总是不正确

[冷静忍耐]

sentence = QString::fromLocal8Bit(str.c_str());试一下

[astro_lee]

QString::size();返回的才是字符个数

[未狂]

你把QString转成了string干什么，多此一举 直接用QString::size()就是了

[Reflux_]

  string s;
  QString sentence;
  while(s!="#")
  {
        cout<<"Please input a chinese sentence:";
        cin>>s;
        sentence=QString::fromStdString(s);
        qDebug()<<sentence.toLocal8Bit().size();
  }
