+ This String class provides base functionality for C++ like Unicode

+ memory allocation) as long as you do not change the string. This class
+ also stores the length of the string, so that many operations are
+ faster than the C-str-functions.
+
+ This class provides only readonly string handling. So you could create
+ a string and you could only query the content from this string.
+ It provides also functionality to change the string, but this results
+ in every case in a new string instance (in the most cases with a
+ memory allocation). You don't have functionality to change the
+ content of the string. If you want to change the string content, then
+ you should use the OStringBuffer class, which provides these
+ functionalities and avoids too much memory allocation.
+
+ The design of this class is similar to the string classes in Java so
+ less people should have understanding problems when they use this class.
