But this is not true. It would only not work if some specific program
had its own "text mode" in which it did this. I have never seen such
a program.
Do you have a real example of one?

None of the Unix standard library routines do this.

You referred to text mode in stdio. In Unix, there is no distinction
between text and binary mode in stdio. Text mode in Unix does not
do any line-end conversion, and does not interpret control-D. It is
a no-op.
