@JoeFriend I would be grateful if you would take a quick look at my "Update 1" and "Update 2" (especially the latter!) in this post on Hermeneutics.Meta about Hebrew fonts. Targetting a unicode range is now a "thing" and easily done, as I'm sure you know better than I do. It seems to me to be a simple, effective, low-cost way of catering to some of the non-Latin font desiderata. Thanks!

Seem to be SE network wide, in fact, in both "beta" and "graduated" sites.

lol, as they say! :) I quite enjoy it -- although it's really it's the opening few pages that are most captivating. It's not exactly downhill from there, but it is outstanding (IMHO!).

I copied in 30,001 characters worth of Bleak House (resisting the temptation to actually read it), and deleted a character. The warning pop-up went away. I clicked "Post Your Answer", and got the second screenshot, that I was now at 30,535 characters. The difference between those two is (almost exactly) the number of lines in my "post".
