EVALUATION This is in fact a bug in the test. It is not updating the ch[1] to set the char to the char for which we want to measure the advance, so it actually measures the advance of char==0 which doesn't esist so maps to the missing glyph, and so that's what's measured. On Vista MS Gothic adds some new code points and specifically maps char==0 so the test fails.
