How many letters does Unicode currently include in the Latin script, no matter the language, but ignoring upper vs. lower case differences?

Latin script in Unicode – Wikipedia

As of version 9.0 of the Unicode Standard, 1,350 characters in the following blocks are classified as belonging to the Latin script

Let’s remove the uppercase letters; and that leaves us with your answer. From eyeballing:

26+30+128+104+14*8+12+12+67+26 = 517

That leaves 833.

If I’m wrong, I’m not wrong by much.
