Description
with prompt_toolkit v1.0 I used PtyProcess for testing and a regex to remove the ansi escapes from the output. the result was pretty straight forward and I could use it for testing.
with prompt_toolkit v2.0 my results following this approach are not usable any more. I assume that has to do somehow with PT2 using ansi escapes differently in output. I am now thinking of a special version of DummyOutput which would preserve the (Unicode) text but eliminates the formatting. I want to extract the lines as a list from the DummyOutput (i.e. ['line0', 'line1']).
I am pretty sure most of this functionality is already implemented in PT2 and I would appreciate comments and pointers very much.

Research direction
Start by locating DummyOutput and the existing prompt_toolkit v2 output and ANSI-handling paths, then compare them with the reported PtyProcess approach. Determine how Unicode text and formatting are represented, and verify that the proposed testing output preserves text, removes formatting, and exposes lines such as ['line0', 'line1'].
