humm... pretty scary... wonder how many other bug are accidentally hidden ?

One issue is that String already enforce the 64K limit (despite
internally using a int32 for the len), whereas OUString, obviously
does not... should we bother enforcing that limit ? including
maintaining a distinction between 'variable-len' (Basic) String and
'fixed-len' String (which is not going to be trivial since they are
represented by the same kind of object)

while on the topic of magic c++ trick:


OUString* a = get_some_OUString_pointer()

*a = a->copy(0,5);

leak or not ?
