No, they are generally avoided in favor of the QString class, which is 
safer, easier to use and works with unicode internally.

See above.

QString was there since always, provided by the Qt library.
Generally when coding in C++ using the Qt and KDE libraries you don't 
really have to think about boundary checking. Sure, there are cases 
when it's not a good idea to access the n+1'd element of an array, but 
this usually doesn't result in memory corruption, only in an error from 
the framework (or in certain cases the n+1 element is added to the 
array).
For strings there are only a few cases when you have to think about the 
length of the string.
