  Well to add functionality with say ANSI you entered an escape 
code and then stuff like offset, color, effect, etc. UTF-8 
automatically has escape codes being anything 128 or over, so as 
long as the terminal understand it, it should be what's handling 
it.

  In the end it's all just a binary string of 1's and 0's.
