unequal sign(≠) in LaTeX painting incorrectly

[cindywu]

To reproduce use $\neq$ in editor.

The temporary solution is to use \mathrel{\char`≠}

KaTeX doesn't really support font overriding, I'm afraid. I'm not sure if it's currently possible to override just numbers and letters and avoid overriding symbols, but that's the behavior you'd want...

You could also try redefining the behavior of \neq to instead do \mathrel{\char`≠} which produces a literal not-equal character which should work in other fonts. You can do this easily via the macros functionality, or via a \def.
