Text_demo 'Load Font' crash

If you try to load the font 'NotoColorEmoji.ttf' from the examples/assets directory (whether copied to the base directory or symlinked) then the example crashes with:

Which I suppose means that the NotoColorEmoji.ttf font doesn't have a color bitmap? Anyways, I was wondering if this should/could fail gracefully and produce a warning about the font instead of a crash? I tried a few other fonts and they work fine.
