Subject: 29.1; ?\N{char_name} reference is wrong
Date: Fri, 15 Sep 2023 22:02:37 +0900
S-exps in the form of ?\N{char_name} return wrong values for some
characters.
The S-exp below inserts a whole list of such characters.
(dotimes (u (1+ (max-char 'ucs)))
(let* ((name (get-char-code-property u 'name)))
(when (and name (not (<= #xD800 u #xDFFF)))
(let ((u2 (condition-case err
(read (format "?\\N{%s}" name))
(error 0))))
(unless (eq u u2)
(insert (format "%X\t%s\t%X\t%s\n" u name u2
(if (= 0 u2)
"error"
(get-char-code-property u2 'name)))))))))
