Dylan Beattie has a thought-provoking presentation for anyone who believes that "plain text" is a simple / solid substrate for computing: "There's no such thing as plain text" https://www.slideshare.net/slideshow/theres-no-such-thing-as... (you'll find many videos from different conferences)

Anybody know more?
The title just talks of plain text though, and plain text usually means UTF-8 encoded text these days. Plain, as in conventional, standardised, portable, and editable with any text editor. I would be surprised if someone talked about plain text as being limited to just ASCII.
