12.1.1.2 Bizarre interaction between `microtype` package and \eqref macro

https://tex.stackexchange.com/landing/r/digest?cta=question&id=757738

I would have thought that if I declare \let\stdeqref\eqref, then the \stdeqref macro and the \eqref macro would be interchangeable.  But here is an example where it fails!  Moreover, this failure is (... 
[macros] [microtype] [eqref] [let]

I'm typesetting my math document in Times New Roman using XeLaTeX and the fontspec package. I'm using mtpro2 as the math font, but I've noticed that certain letters, such as u, v and w, look quite ...

12.1.1.5 How to get spaced dots in unicode-math

https://tex.stackexchange.com/landing/r/digest?cta=question&id=757760

The unicode-math package re-defines ellipsis to be the ellipsis character in whatever font you're using, instead of spaced dots. This looks bad in my opinion, and violates the guidance on ellipses in ...

https://tex.stackexchange.com/landing/r/digest?cta=question&id=757545

Using the BaskervilleF font with instructions from here, \mathit{ff} produces fb instead of ff. Normal text, \textit and normal math modes are unaffected.
