@ Josh Rosenberg Sorry, I mistook "follow" as "be followed by". Thanks to your explication, the document is coherent. I admit that I cannot conjure up any better altnernative.

I noticed that "cased character" are explained via the footnote: https://docs.python.org/3/library/stdtypes.html?highlight=istitle#id6

So it may be better to add a footnote for "uncased characters" as well, like ones in "str.istitle()" and "str.upper()".

By the way, the footnote for "cased character" is a bit confusing because of the curt abbreviations "Lu", "Ll", and "Lt". I did not get these until I fount out they are related to general category of unicode, so we could add a related link pointing to a related Unicode document.
