QTextStream - problem reading accented - special chars

fox1969

Goodnight to all from north of italy, from LUG Govonis Finale Ligure.

I'm using a Debian Testing with Qt Creator 2.8.1Based on Qt 5.1.1 (GCC 4.6.1, 64 bit)

I made a regex for hotel booking for parsing mail (strings) of this type:

@PL - Krasinska, Katarzyna
dal 16.07.2013 al 27.07.2013 2 adulti, 3 bambini

NL - Bak, Bert
dal 27.07.2013 al 03.08.2013 2 adulti, 2 bambini

DE - Großmann, Heiko
dal 03.08.2013 al 10.08.2013 2 adulti, 2 bambini@

You can see there are particular characters like ß.
I have to prepare a regex to retrieve name, surname, arrival...etc....
I wrote a little function to read the file and tested the returned string with a TextEdit. The function goes on without compile errors but....i cant see the ß char.
In this case i have only one but it can happens that...there are other chars, for example umlaut or other accented unicode chars.

If i test the TextEdit with this:
ui->textEdit->setText("Großmann");
All function good but not with my text file.
This is the code of reading function:

@
QString MainWindow::read(QString nome_file )
{
QFile mfile(nome_file);
QTextStream in(&mfile);
//in.setCodec("UTF-8");
//in.setAutoDetectUnicode(true);
mfile.open(QIODevice::ReadOnly | QIODevice::Text);
QString data = in.readAll();
return data;
}
@

There are two lines commented but...if i don't comment them....all is the same.
The returned variable is tested with this simple function;

@
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);

mail_str = MainWindow::read(file_name);

ui->textEdit->setText(mail_str);

}
@

This is the wrong output:

This is my pro file, excuse me but i have no experience wit bq quotes so i use code quotes.
@
QT += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = PoggioBlumen_Mail2
TEMPLATE = app

SOURCES += main.cpp
mainwindow.cpp
blumen_mail_cl.cpp
prenotazione_cl.cpp

HEADERS += mainwindow.h
blumen_mail_cl.h
prenotazione_cl.h

FORMS += mainwindow.ui

@

My EDITOR settings are:
Default encoding : UTF-8
UTF-8 BOM : Keep if already present.

Tanks in advance! Before desturb you i spent several days with google to find a soluion but...nothing!
I tried reading the file in a loop line by line but nothing changes..... :-(

Any idea to solve my problem?

I'm studying various tutorial on the web without finding anything and i'm sad to....change complitely IDE RAD only for some characters.....

Before i used Visual C# on WIN without problems...now i want to migrate but it's not easy.

Thanks and excuse me.

Hi, which encoding your target text file is used?

fox1969

if i use the command file from the linux console i have:
MIME entity, ASCII text

if i use file -i to check the mime i have:
text/plain; charset=us-ascii

Is this your question?
