I question the "vast" quantifier.

Zsh has many SIMPLE PROMPT ESCAPES and CONDITIONAL SUBSTRINGS IN PROMPTS 
-- see zshmisc and / or zshall manual pages.  But they all seem to be 
specific to what appears on the prompt line(s).

This starts falling apart when you print terminal control characters / 
escape sequences used to alter the terminal window title or re-define 
the default terminal background / foreground colors and / or resize / 
reposition the terminal window itself.

N.B. there is very much so a difference in re-defining the terminal's 
current default vs specifying colors in the actual output.

Zsh has the most feature rich prompt support that I remember seeing. 
But even that doesn't cover all the things that I do.  Hence why Zsh 
includes the %{...$} and even the %G to alter how Zsh does or doesn't 
count characters output to the terminal.
