Full-screen App with Terminal Characters

[Queuecumber]

I'm writing a full screen app that takes input from multiple files which are being written to by remote processes. These processes use tqdm to display progress bars (their output is redirected to the files). If I read the files using standard python and use the print function, the bars display fine. Now I want to display all the files at the same time so I'm using this library to make a split screen full screen app. The problem is the display looks like this:

with each update printed on a new line preceded by ^M

is there a way to display this properly?

The actual character that it's using is \x1b[A "cursor up"

I see that it's supported in some capacity here: https://github.com/prompt-toolkit/python-prompt-toolkit/pull/1080/files#diff-0a8bfa00afa04946b2b3c8faaa853e12L58 but I'm not sure how to translate that into what I'm doing. I currently am writing the strings to a TextArea using ANSI formatted text with the tricks from #711
