ogonek::text is intended as a Unicode-based string class. Not as a glorified container of characters, like
std::basic_string, but as an actual piece of Unicode text.
text is not about storage, so it delegates that to another container. That container can be customized, yielding a varied range of performance characteristics suitable to any situations. One could have a Unicode text array, similar to
std::basic_string, or one could have a Unicode text deque, or even a rope.
