Storyline 360--HTML5 text scrambled

So—what fonts am I not supposed to use??? I've used Calibri, since it's the default in MS Office. Why doesn't that work since most everyone using the latest MS Office has it? I've used Arial in the Title slide alone and it still is swapped out or scrambled. Player font sizes are enlarged, too, even they are unchanged from 100% in the player settings.

This is a high-stakes presentation and is highly visible and about to be promoted. This needs to get resolved immediately—so far solutions I'm reading here aren't helping.
