As it turns out, the Unitex code is not compatible with the standard libraries, for example std::unique_ptr, using them would limit the ability to compile the code under architectures, platforms or other C/C++ compilers that are not distributed with implementations of the standard libraries.

Instead of Vector you should use List_* structures or other available structures. This, in the same way that instead of std::string you should use unichar, uString, or UnitexString.
