I'm not aware of one.

But my ignorance doesn't preclude it from existing.

I'd suggest skimming / reading the XTerm Control Sequences page.

Link - ctlseqs(ms) - XTerm Control Sequences
  - https://www.invisible-island.net/xterm/ctlseqs/ctlseqs.html

N.B. the ctlseqs page is the most complete that I've found for XTerm -- 
which makes sense given the source.  The only other thing beyond that is 
to delve into the manuals for various other terminals.

XTerm should implement everything on it's ctlseqs page.

I've found that most of the control sequences that XTerm and fancier DEC 
terminals support aren't even a glimmer in the eye of most terminal 
emulator programmers.

Finally, I find the idea of allowing programs to read existing text on 
the screen to be a potential security violation.
