Just last week, we had an issue with a contractor's mail client. The contractor implements the server-side of $project, we implement the device side, which is essentially a microcontroller talking to an ESP32 to exchange data with the server. We suspected a communication error, so I asked for the debug log output from the device. And what I saw looked like a huge stupid error on the contractor's side. We all know clever people trying to use Word as a code editor, getting StupidQuotes (” “ „ ⹂) instead of straight quotes (") in the way, and confusing the crap out of compilers, interpreters, and parsers. And the debug log looked just like that: StupidQuotes everywhere, breaking any attempt to parse the messages coming from the server. But strangely, also straight quotes emitted by code on the device had mutated to StupidQuotes. And surely, the Mail headers were full of Microsoft fingerprints, his stupid mail client had auto-"corrected" the quotes found in debug log text he copied into the mail.
