    Please show your code.

    What encoding do you use? How do you pass your string to the printer?

  • Hi friends,

               @    @QString ItemPushButton::name_check(QString str)

    QRegExp [removed]"#([0-9]+);");
    QStringList list,list1;
    int pos = 0;
    int length;
    while((pos = expression.indexIn(str,pos))!=-1)
    list << expression.cap(1);
    QString v;
    length = expression.matchedLength();
    QByteArray ba = v.toUtf8();
    QString str1 = QString(QChar(v.toInt()));
    list1 <<str1;
    pos += expression.matchedLength();
    foreach (QString s, list) {
    str = str.replace("#","");
    str = str.replace(";","");

    foreach (QString s, list1) {
        str = str.append(s);
    return str;


    This is my code,,In here i get the chinese character string,,, after that i pass this string to printer directly,,,In the receipt page other characters are comes correctly,,,the chinese character only the problem,,It prints the Question mark instead of chinese character,,Please give me a suggesstion,,,Thanks,
