Write Qt program to a language with special symbols

[hakermania]

I though that this count be done with the use of tr() but I was wrong...
I am trying to place this text to a button:
Déplacer à l'image &suivante
In french it means "Move to Next image". I place this text into the button with this way:
ui->nextButton->setText(tr("Déplacer à l'image &suivante"));
The Qt Creator, after compiling, show the button's text like this:

As you can see the special character is shown wrong. Is any Qt can recognise these special characters?

I agree, this is odd behaviour ...

My suggestions would be to check the encoding of your source file - if it's ASCII the special characters might be conflicting with Qt's Unicode text system - make sure it's some variant of Unicode. That or look up the Unicode codes of é and à and use backslashes to put them in ...

If that doesn't work you might need to have a look at QTextCodec::setCodecForTr(). I'm not sure what codecs are available but there should be one which supports French letters.

I'm not 100% certain about this but hopefully one of the methods above will work.

Salut hakermania,

if you don't want to change the whole codec you can use QObject::trUtf8(). But you have to make sure, your file is encoded with UTF-8 too.

Thanks for your suggestions. Lykurg, I used your suggestion and I finally found a solution!
I had to use button->setText(QString::fromUtf8("String here"));
and where there were special characters (like à ) I had to replace them with utf8 special from (e.g. é is written \u00e9)
There are several webpages where you can find these tables that specify the special characters for every special character.
So the action from this

ui->nextButton->setText(tr("Déplacer à l'image &suivante"));

ui->nextButton->setText(tr("Déplacer à l'image &suivante"));

To copy to clipboard, switch view to plain text mode 

should be done

ui->nextButton->setText(QString::fromUtf8("D\u00e9placer \u00e0 l'image &suivante"));

ui->nextButton->setText(QString::fromUtf8("D\u00e9placer \u00e0 l'image &suivante"));

To copy to clipboard, switch view to plain text mode

Try to use your special letters direct. You just have to make sure that your *.cpp file is encoded in utf8. So you will save time for escaping them.

ui->nextButton->setText(trUtf8("Déplacer à l'image &suivante"));

ui->nextButton->setText(trUtf8("Déplacer à l'image &suivante"));

To copy to clipboard, switch view to plain text mode

Nice info, thak you all for this post

[hakermania]

No, i've tried this. I need to place these strange symbols....

Aren't the contents of tr() supposed to be English?

[Lykurg]

Try the attached project without changing the file encoding and see if it works.

No, you can also perfectly write latin in tr(). The language just should fit in ASCII in normal case.
