Delphi-PRAXiS - Delphi and AI[5]: Encoding a multi-line string

Recently I had to convert a multi-line string into a single-line string value for storage (ignore the 'why' of it; let's just blame it on a legacy code). My first idea was to do a Base64 encode of the string, but I was in a mood for some fun and so I asked my friendly AI helpers:

"I have a multiline string containing newline ASCII characters (TMemo.Text). I want to change it to a single-line string with only printable ASCII characters. I could do that with BASE64 encoding, for example. I would, however, like to keep the text as much readable as possible by "encoding" only non-printable characters. Is there a simple way to do that?"

Let's see what they came up with!

Full transcripts, as usual, are on

GitHub. This time I had also created a program containing all implementations.
