That's only for the recommended default behavior. There are many

The specific wording in POSIX
Again, LC_CTYPE does *not* affect source file interpretation.
I understand what you're saying. What I am saying is that if this
is how c99 behaves it's in conflict with POSIX because LC_CTYPE
is exactly how source file interpretation is specified to be
controlled:
LC_CTYPE

Several of us don't want UTF-8 quotation marks in diagnostics in our
environment (Jove subshells). We'd like a way to turn them off. We don't
think that they are a bad idea but they are bad in our environment.
