This a unicode-math bug, please report to unicode-math.

P.S. Please surround your example with ‘pre’ HTML tags or indent it with four spaces to print code correctly

@khaled: I see it now (sorry for not testing with other UM-fonts first). Also fixed the example code. I also see that you have reported there yourself. Should I just try to write under your post, and see if someone does anything about it or?

BTW, your \textup{\textsf{T}} ends up using CM sans not the math sans from the math font, no idea why.

from xits.

Because \textsf chooses the text font and \mathsf chooses the math font :)

Ah, thanks for telling! Learning something new everyday; didn't know that \mathsf yileded upright text.
