    Here a simple code.
    @
    if (qstr==my_name)
    ui->textEdit_In->append(tr("ID_REGISTER_NUMBER=%1=%2=").arg(my_name).arg(qstr));else
    ui->textEdit_In->append(tr("Why?????ID_REGISTER_NUMBER=%1=%2=").arg(my_name).arg(qstr));
    @

    and the output :
    Why?????ID_REGISTER_NUMBER=Eng C. Born1=Eng C. Born1=
    It works in a smaller program.
    I just don't understand why it acts this way.
    Any suggestion?

    Thanks.

      Strange. You did not show us how you initialise those strings, though.

      Try running a QString::compare() on them to see what QString thinks about them.

        OK, I find the bug. I can only see when I bring the code to Linux. TextEdit in Windows didn't print an extra char while on Linux it does print it out.
        But I still can not understand why the same codes work on the smaller program.
        Any how, the problem is solved.

        Thanks anyway.

          Probably some codec issue. Be sure to store cpp files as UTF-8.
