Calling textToModel() with a space character (' ') throws a runtime error.
This appears to be a regression. It should not crash the function.

This currently breaks the Typography 2.0 tutorial on the p5.js website. (https://beta.p5js.org/tutorials/typography-20/)

Steps to reproduce

1. Open a WEBGL sketch
2. Load a font
3. Call:

font.textToModel(' ', 0, 0);

Throws:
TypeError: can't access property "vertices", n is undefined

i’m up for this! i’d love to know what the expected behavior should be from the maintainer side. should textToModel(' ') return null / an empty model, or just fail gracefully without throwing?

Thanks @skyash-dev! I think an empty model makes sense. This also used to work in earlier 2.x versions, so feel free to take a look at this sketch https://editor.p5js.org/davepagurek/sketches/Ty-01oHgN to see what gets returned, I assume it's also an empty model.
