Hi Mark, Can you please review the aa2u package in GNU Elpa? https://elpa.gnu.org/packages/ascii-art-to-unicode.html In there, there is this function which triggers error after this change[1]: (defun aa2u-1c (stringifier &rest components) "Apply STRINGIFIER to COMPONENTS; return the UCS char w/ this name. The char is a string (of length one), with two properties: aa2u-stringifier aa2u-components Their values are STRINGIFIER and COMPONENTS, respectively." (let ((s (string (cdr (assoc-string (apply stringifier components) (ucs-names)))))) (propertize s 'aa2u-stringifier stringifier 'aa2u-components components))) Can you please update the package so that it works whether ucs-names is a hash-table or a list? I also realized that it broke the counsel-unicode-char interactive function in the counsel.el package too: (defun counsel-unicode-char (&optional count) "Insert COUNT copies of a Unicode character at point. COUNT defaults to 1." (interactive "p") (let ((minibuffer-allow-text-properties t) (ivy-sort-max-size (expt 256 6))) (setq ivy-completion-beg (point)) (setq ivy-completion-end (point)) (ivy-read "Unicode name: " (nreverse (mapcar (lambda (x) (propertize (format "%06X % -60s%c" (cdr x) (car x) (cdr x)) 'result (cdr x))) (ucs-names))) :action (lambda (char) (with-ivy-window (delete-region ivy-completion-beg ivy-completion-end) (setq ivy-completion-beg (point)) (insert-char (get-text-property 0 'result char) count) (setq ivy-completion-end (point)))) :history 'counsel-unicode-char-history :sort t))) [1]: http://git.savannah.gnu.org/cgit/emacs.git/commit/?h=emacs-26&id=96c2c098aeed5c85733577ebbdaf33af6fbb59e9 -- Kaushal Modi
