It doesn't make any sense for the contents of input files to be a
factor in whether or not an application is running in a conforming
environment.

In the particular case of character encodings, the standard
requires interfaces such as mbtowc() to fail with EILSEQ if
an invalid character sequence is detected.  It could not make
such a requirement if the presence of an invalid character
sequence in the input meant that the function was being called
in a non-conforming environment.
