I thought that you can guess that it represents Unicode code point.
Of course, "The Book" pays lip servers: "However, a “character” isn’t
really a concept in Unicode, so your human intuition for what a
“character” is may not match up with what a char is in Rust."
But who pays attention to lip service?
You can be reasonably sure that 99.99% of Rust programmers use the word
'character' in the meaning 'Unicode code point'.
