On Windows, std::tmpfile() returns NULL with errno 22 when %TEMP% contains a character outside the ANSI code page, where GetTempPathA returns '?' in its place. Fifteen tests that capture output through it aborted. TemporaryFile::Open() opens a unique delete-on-close file under temp_directory_path() with _wfopen; other hosts keep std::tmpfile().
