\Omega is not rendered #2

Closed zcysxy closed 2 years ago

zcysxy commented 2 years ago

A super weird bug 🤣: \Omega is not rendered. A minimal working example:

\begin{document}
\begin{tikzpicture}
\draw (0,0) node {$x\omega\Omega\Gamma$};
\end{tikzpicture}
\end{document}

The result is $x\omega\Gamma$, the $\Omega$ is missing 😂

Weird! I'll try to look into this when I have time.

Do you know whether this happens with any other symbols?

zcysxy commented 2 years ago

I tested common greek letters and math symbols, and found another one: \otimes.

Unlike wrong syntax or unsupported packages like \mathbb, which break the output image, \Omega and \otimes take up some space but are not rendered.

Thanks, that was useful info!

It turns out that \Omega and \otimes were represented by the "soft hyphen" character in unicode, which is invisible. I came up with a hacky workaround where I patch the fonts and move the soft hyphen glyph to a different character.

This is now solved in 0.4.0.
