Description
Issue Summary
There is a difference in rendering if the macro \sum or the corresponding unicode character ∑ is used. LuaLaTeX rendering leads to identical placement of limits, while MathJax always treats limit positions for ∑ with inline style.
This issue occurs with Safari and OS X.
Steps to Reproduce:
Rendering
$$ ∑_{k=1}^{n} - \sum_{k=1}^n $$
yields the following output:
With LuaLaTeX on the same snippet both sum signs and placement of limits look identical.
Technical details:
- MathJax Version: 3.2
- Client OS: (e.g., Mac OS X 10.8.4)
- Browser: (e.g., Chrome 29.0.1547.57)
