Sorry, been so busy trying to get this instance running properly, haven't had time to reply to the majority of people! So I have actually tried using ascii diagrams many times in the past, but it's always failed. I think people just don't want to use another tool to modify the charts, especially because in the one I used I am pretty sure (been a long time now) that once you exported it you could no longer edit it with the tool anymore. These days I simply use one of the text based diagramming tools like D2, mermaid, etc. https://text-to-diagram.com/
