"When /Zc:trigraphs is specified, the compiler replaces a trigraph character
sequence by using a corresponding punctuation character. To turn off trigraph
substitution, specify /Zc:trigraphs-. By default, /Zc:trigraphs is off."
Yet:

..\..\sandbox\win\src\win_utils_unittest.cc(103,18) : warning(clang): trigraph
converted to '\' character [-Wtrigraphs]
pipe_name = L"/??/pipe/mypipe";

Looks like it's not off by default in clang-cl. It should be.</pre>
