Maybe charbitism?  

Separate from character processing, there are many uses for 
an eight bit type. Processing image data using eight bits per
pixel, or eight bits per R, G, or B, per pixel. That should 
be completely orthogonal to the bits per character.

Do note that Java does just find with a 16 bit unsigned char,
and signed 8, 16, 32, and 64 bit integer types.
