[Solved] Qt 5.1 statusbar character encoding bug

[eMixam]

Hello,

I may have found a bug in the QStatusBar in Qt5.1.

My locale is French and I'm trying to display accents : "éàêùç ..." and all of them appear as black "?" if I compile with Qt5.1.
If I compile with Qt4.8.4 the accents appear.

You can make the test, just create a new project application and add after "ui->setupUI(this)" :
@ui->statusbar->showMessage("éàêùç");@

Can you confirm it's a regression / bug or did I miss something ?

Thanks in advance.

EDIT : forgot to say that the others texts, used in QLabels are displaed correctly.

Hi,
Is the exec-charset of your application is UTF-8?

I do think so since if I build my QString with QString::fromLatin1(), the accents are displayed correctly.

What I don't understand is why do I need to specify it only for the QStatusBar ?
In other QLabels and even in QML Text they are displayed correctly.

It means that the exec charset of your application is latin1! So you need to use QLatin1String or QString::fromLatin1() to convert the string from char* to QString.

Are your sure that:

@
ui->label->setText("éàêùç");
@

works in your source code?

Okay, so QString is using UTF-8 as default hence the need to use QString::fromLatin1() ...

Nope, does not. This means that it's the Designer who does the conversion.
I still don't know how the QtQuick part of my application does the conversion of units.

Thanks for your help.

EDIT : I know why the QtQuick part displays the accents : it takes its data from a XmlListModel and the XML file is encoded in UTF-8 :)
