I'm afraid not. The powers that be interpret the final sentence of 14.3(7),
"The effect of input or output of control characters (other
than horizontal tabulation) is not defined by the language."
to mean that, for example, outputing ASCII.NUL via TEXT_IO can result in a
file that ends at the NUL, or can output an 'A' instead, or....
