   There have been actual uses of trigraphs.  Richard Heathfield posted   
   this on this newsgroup in 2010 :   
      
       Yes, they are still needed, for example in some mainframe   
       environments.  They make the code look astoundingly ugly, but   
       they do at least make it work. It is not uncommon for "normal"   
       C code to be written and tested on PCs, then run through   
       a conversion program to replace monographs with trigraphs   
       where required before transfer to the mainframe for final   
       testing. That way, you get the readability where it matters,   
       and the usability where /that/ matters.   
      
   But trigraphs have been removed in C23.
