You didn't answered my questions :).
  The most important one is: can we have  *A single* String class and *A* 
single sting wrapper for each UTF-X variant?

  Personally I'm not going to waste my time learning 10 sting wrappers and 
classes just to make some pico optimizations like:

QString ext = QLatin1String("exe"); // it's terribly wrong and people which 
are doing this mistake must be stoned to death!

QString ext = QStringLiteral("exe"); // it's so good and it will save the 
planet from extinction!

// But
QString ext1 = QLatin1String("exe") + ext; // it's ok
// and 
QString ext = QStringLiteral("exe") + ext; // it's a abomination!

// Even more
QHash<QString, QString> test;
test[QLatin1String("key1")] = QLatin1String("some text %1").arg(1); // wrong
test[QStringLiteral("key1")] = QStringLiteral("some text %1").arg(1); // wrong 
again
test[QLatin1String("key1")] = QStringLiteral("some text %1").arg(1); // still 
wrong
test[QLatin1String("key1")] = QStringLiteral("some text %1").arg(1); // 
victory !!!

Am I the only one which finds situations silly ? Of course there are more 
examples with the other String wrappers/functions in Qt, but I think is enough 
to show how crazy is the situation.

Cheers,
BogDan.
