> leaking the existence of something terrible inside
If you should get the opportunity to look at a raw (DNS) NXDOMAIN passive DNS (PDNS) feed there's a lot of plain brokenness, but the nuggets can be truly alarming. This is what happens when translating between naming services: naming services typically have application domains, and names in one context are interpreted differently in another. Bobby Tables is well known, but how about that special file "-rf"? Was a time when the happy path for Active Directory essentially trusted DNS domain names implicitly for things like file shares. Sounds ok until you realize executable files might be on those "drives".
(Honestly I don't find the string "MS-DOS" anywhere in that document.) (Edit: Did find the reference to e.g. CON, LPT1...)
If my memory serves me well, 7F was historically used for the «Delete» key code, and outputting it on a real terminal (or in terminal emulator), would result in the in-place text deletion from the output.
Not that it has been relevant in last 2-3 decades tho.
