Applications and text-processing libraries are free use an internal text encoding or data structure, if you will, which does not suffer from the drawbacks. Conversions to encodings suitable for data exchange (e.g. UTF-8) are performed at the I/O boundaries.

Sure, and if stuff lives inside your "application and text-processing library" for long enough and performs enough of the thusly optimised actions without leaving, you might even amortize the cost of the work you did at the edges.

But probably not.
