Glyphs slightly off center

[masaeedu]

Hello. I recently installed the ttf version of scientifica and started using it in Konsole, but am noticing that some glyphs (the plus, times, boxtimes and arrow symbol from my experience) are slightly but noticeably off center when surrounded by parentheses. The screenshot below shows that they seem to be slightly biased towards the right.

Do you think this is an artifact of my setup or something to do with the font itself?

PS: Thanks for your work on scientifica and curie, they're two of my favorite fonts!
