Not equal (\ne) sign doesn't render correctly the slash sign

[henrroga]

It seems the slash sign on top of the equal sign is broken.

I have the latest version of Katex in my project. Below is a screenshot taken in the latest version of Firefox. Also in Chrome is the same thing.

If you go to the demo on katex.org, do you see the same thing? I see:

It looks like you either aren't including the font files, or they're getting overridden in the CSS. Note in particular how the numbers look very different. If you send a complete working example, we can try to help.

True, the font is overriden with a Google Font. Now that I removed it it's okay, but I have to use my font of choice. Everything else with math expressions seems fine with this font (and other; I also tried Roboto), but this equal sign is the only thing until now that I have found to render incorrectly. Anything else I can do?

[edemaine]

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...

[edemaine]

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.

I see. Great, thank you so much!

re: workaround from @edemaine, thank you!

macros looks like this for me:

katex.render(
  text,
  element,
  {
    macros: {
      '\\neq': '\\mathrel{\\char`≠}',
    },
  },
)
