In the printing world inkjet printers for industrial use use a file format that is all RS, GS, US, and FS characters. It had no line breaks instead it used a RS character at the beginning of a record. It would routinely break if people tried to open in a text editor. Nothing wants to deal a 300mb file consisting of a single line. Ended up writing my own library to manipulate the files and used a lot of tr, see, and awk in the command line. It was a pain only because modern editors have forgotten control codes
