To bridge that, I actually built a font that keeps those phonics-aligned features and allowed us to use stories from things like Project Gutenberg. It’s based on the open-source TeX Gyre Schola, ( kind of like what is used in the Spot books) with OpenType features that auto-connect common digraphs (like “th”, “sh”, “ch”)— but in a way that can gradually phase out. Just put it up on GitHub if you're curious: Reading Guide Font. Open for any feedback or criticism!
