If you are just handling 256 or 4906 possible chars, then an ordinary
array will be both easy to code and very fast. The highest named
entity is 9830 &diams; 0x2666 black diamond suit.
There are 2^16 = 65536 possible 16-bit unicode chars. Which chars do
you transform?

Refactor early. If you procrastinate, you will have
even more code to adjust based on the faulty design.
