      Most symbol names are written with letters, digits, and the
    punctuation characters `-+=*/'.  Such names require no special
    punctuation...

My impression is that manual passage was written with only ASCII
characters in mind.  But since Emacs has allowed Unicode characters in
symbol names for a long time now, I don't think we should all of a
sudden declare "letters" to mean just [a-zA-Z].
