Hello, I am having issues—which I thought were related to this thread—with math accent usage under XeLaTeX & unicode-math with XITS. When I use a \tilde on a character that has sub/superscripts, the tilde gets very wide, and even crashes with the superscript. Is there something that I'm missing, or need to update? The attached pdfs show the output I get under XeLaTeX and pdfLaTeX.
As a side note, the prime symbol of XITS seems a little too thin compared to
the computer modern one. Is there a way to make it thicker? When typesetting
double column documents in 10pts, the prime becomes quite hard to see.
