Is the benefit of doing this switch at all large enough? Even though it  
becomes somewhat easier to deal with 💩 you still have grapheme clusters  
you will need to work around. That is, it is not clear code points are the  
right abstraction point and then you might as well keep 16-bit code units  
with support for surrogate code points so you can render everything above  
BMP too.
