Fun fact, ctrl-v in bash sets "verbatim insert" mode for the next character, so you can type a ^D "character" by doing "ctrl-v ctrl-d".

It’s not bash, it’s the tty device driver. Applications can switch between the ‘cooked’ mode (which recognises it as EOF) and ‘raw’ mode (which passes it through) by performing some ioctl I don’t really want to look up right now.
