Describe the bug

Recently I have decided to use custom font instead of default font. I have a little problem because some glyphs don't stretch up and it looks wierd when I display it. I don't know if there is a problem with my font or there is a bug in the library.

To Reproduce

  1. Download font from link https://drive.google.com/file/d/1eYEoNWXoonjhSVx_AN_H0pghTOnjT8WC/view?usp=sharing
  2. AddOverride above font
  3. You will see that some glyphs don't stretch up ( Newton symbol, square roots)

Expected behavior

All glyphs should stretch up.

Additional context

Screens (Newton symbol, square root)

Does your font set OTF math tables? Without correct information you will not get stretched glyphs.

Ah a TTF font. You should edit your font to use OTF math tables instead.

Hey. I converted my font to OTF and I have a little problem. When I add my font, sometimes text is not visible. I thought that there is something wrong with my font, but I added default CSharpMath font and this bug also occurs. See screen below.
Here is the code:
Assembly assembly = Assembly.GetExecutingAssembly();
using (Stream stream = assembly.GetManifestResourceStream("latinmodern-math.otf"))
{
CSharpMath.Settings.GlobalTypefaces.AddOverride(new Typography.OpenFont.OpenFontReader().Read(stream));
}
textView.LaTeX = "Sample text $$x+3$$";

As you see, when I AddOverride default CSharpMath font, a part of text is invisible. Is there something wrong with above script?
