Is there any character like that?

[Aga Tentakulus]

   

That's just one of the problems.
So is the difference in spelling (already mentioned).
Here is an example (Latin) from an exercise at the University of Zurich.
Red: Middle Ages, blue: modern times. This change took place around 1400.
Even the idea that the scribes used both spellings, depending on their training, reveals the problem. I don't even want to think about regional differences.
So I wonder if a normal AI can help me at all.
I use Google. Why? It's the 1.5 million comparison sentences that also come from old books and not just from today's textbooks.
The disadvantage is that I have to have already looked up the words in the dictionary before I enter them. Just to see if the meaning changes too much, or if it's just nonsense.
