The libraries in the String Libraries package can be used to process strings which
are UTF-8 encoded. The basis is the IString interface from the String Segments library. Using this interface, the strings can be passed to the respective functions
by reference. For example, to create an IString instance, the GSB.UTF8String function block from the Generic String Base library is provided.
