Nope, sorry but it won't.  You had me up to the "most likely" part.  The 
behavior is undefined. (See section A.2.5.2 Character Constants of the
Ref. Manual in K&R 2)  What the compiler is most likely to do is something
random. (ie your pcc based compilers like it, gcc gives a warning then
doesn't print it.  Sun cc gives no warning, then doesn't print it)
