Pasting emoji in QT QTextEdit

I'm trying to paste emoji's in the QT QTextEdit box but it's not getting recognized and it's showing as ??? or [][]

I'm not talking about smiley, I'm talking about emoji.

How can I go about making sure that QT's QTextEdit accepts emoji and displays them correctly?

Thank you.

Got it based on the helpful answer below:

SOLUTION:

    QFontDatabase fontDB;
    fontDB.addApplicationFont(":/Resources/fonts/seguisym.ttf");

    QApplication::setFont(QFont(QStringLiteral("Segoe UI Symbol")));
Solution

  • A considerable number of emoji characters are in the Unicode Standard. If you're, for example, developing with Qt 5.3 in Mac OS X 10.9, pasting emoji characters in text edits should work as it does when pasting any other character.

    The reason why your application is showing ?'s and/or []'s is because the current font (perhaps the default system font) doesn't provide representations for emoji "characters". You can find a proper font out there in the web. Check this for reference.

    Then you can add the font to your Qt application

    QFontDatabase fontDB;
fontDB.addApplicationFont(":/A Font Supporting Emoji.ttf");

    and set it as the font for your application or only your QTextEdit if you prefer

    setFont(QFont(QStringLiteral("A Font Supporting Emoji")));

    With this your app should be able to display emoji.
