    @kshegunov said in QString convert unicode:

    wchar_t buffer[5]

    say me the follow:
    'inicializando' : no se puede realizar la conversi¢n de 'QByteArray' a 'char *'
    No hay disponible ning£n operador de conversi¢n definido por el usuario que pueda realizar esta conversi¢n, o bien no se puede llamar al operador

    In other words when i do this

    wchar_t buffer[5];
    QString string = QString::fromWCharArray(buffer);
    char *utf8encoded = string.toUtf8();
    

    I can't do the conversion.

    You really should check the docs on this.
    I've made a minor mistake, but it's easily correctable.

    QByteArray utf8data = string.toUtf8();
    const char * utf8encoded = utf8data.constData();

      one question normally i think must show unicode text like this :

      Normally i can do this
      QString::fromUtf16((ushort*)buffer)

      But i have one problem with this only show me in unicode when i am using some modificator like ctrl. It's for one keyboard in different languages.

        I don't understand the question. Unicode has little to do with control or with the keyboard, it's an encoding for text, not a device driver ...

                That still doesn't explain what you are trying to do.

                Why do you need all these conversion ?

                  @SGaist i'm trying to do keyboard in different languages and like i was trying to show key's in other languages like(german or others..) i couldn't because i can't get unicode text to translate it.

                    Something like the QtVirtualKeyboard module ?
