Originally created by @PankajBhojwani on GitHub (Jul 9, 2019).

Summary of the new feature/enhancement

We need to support more VT sequences and special characters so that when we establish non-Conhost connections those sequences/characters are dealt with. VT sequences such as erase-in-line and special characters such as BEL should be implemented.

Proposed technical implementation details (optional)

VT sequences need to be implemented in TerminalDispatch.hpp/cpp and special characters need to be implemented in Terminal.cpp - in the _WriteBuffer function (these files are in TerminalCore). For reference for how these functions could be implemented, see adaptDispatch.cpp (in TerminalAdapter).

I'm building out a specification that we will be using to track VT sequence support. See https://github.com/microsoft/terminal/pull/1884
