What is the \? string escape sequence in D?
It’s just to escape
?, a literal question mark.There really is no reason for it to be in D, but it existed in C and C++ in order to avoid the question mark being interpreted as a Trigraph. D doesn’t have Trigraphs, so its inclusion must simply be for some added backwards compatibility with C and C++.
