A comparison of Grantha script characters in manuscripts compared to modern typographic representations, using Śiścepālavadhaha Vyākhyāsahitā from EFEO's archive (EO‑1367).
Note: This is not an exhaustive list of all the characters, but rather a selection of characters that I found extremely difficult to identify. I hope this can be a useful reference for others who are interested in reading Grantha, and also a starting point for further exploration of the visual diversity of Grantha script.
