As usual, this is purely a font issue (on both ends).
Since mathoid configures mathjax-node to use a math font that does not include glyphs for those unicode points, the rendering can be poor.
On a machine without compatible fonts, Gecko's rendering is just as poor.

@Pkra do you have a suggestion for a particular font? I know that there has been a lot of discussion and research about math fonts, but I honestly don't know the results. Is the documentation
Note that not all mathematical characters are available in all fonts (e.g., Neo-Euler does not include italic characters), so some mathematics may work better in some fonts than in others. The STIX-Web font is the most complete.
from http://docs.mathjax.org/en/latest/options/SVG.html#font still up to date or are there some tricks we could play to gradually improve the default font "MathJax TeX" to solve the problem at hand.

I don't think I'm a position to make a suggestion. Too many factors come into play that are up to MW and WM.

There are no easy tricks for contour integrals that are reliable, I think (but I might be wrong since my TeX hacking foo is limited).
There are at least three paths MW/WMF could consider: switching to a different font that supports glyphs, adding fonts, and extending MathJax's font fallback chain. All of these require varying amount of work (the first one primarily testing).
Maybe a virtual F2F of relevant people at MW/WMF would be helpful.
