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.
