   Yes; looking at the minutes now, I can see this was far more   
   controversial than what I remembered about trigraphs, and likely   
   wouldn't have happened if WG14 had required strong consensus then.   
      
   But I think Heathfields'd use case couls still work in C23 if we   
   consider that conversion program together with the compiler on the   
   mainframe to be the C implementation.
