Inserting an unicode character

Inserting an unicode character

[Alberto Simões]

Hello

Is there any way to visit an unicode table from within emacs? Or, for
instance, inserting the caracter using its name.

TIA
Alberto

The emacs sources come with a file called »UnicodeData.txt« (in admin/unidata/). You can do
all kinds of cool things with it. To insert a character by name:


(defvar unicode-character-alist nil)
(defvar unicode-character-names nil)

(defun unicode-get-names ()
  (let (unidata)
    (with-temp-buffer
      (insert-file-contents "/path/to/emacs/admin/unidata/UnicodeData.txt")
      (goto-char (point-min))
      (while (re-search-forward "^\\(?1:[[:alnum:]]+\\);\\(?2:.*?\\);" nil t)
	(add-to-list 'unidata
		     (cons (downcase (match-string 2)) (string-to-number (match-string 1) 16)))))
    (setq unicode-character-names (mapcar 'car unidata))
    (setq unicode-character-alist unidata)))

(defun unicode-insert-by-name (name)
  (interactive
   (list
    (progn
      (unless unicode-character-names (unicode-get-names))
      (completing-read
       "Insert unicode character named: "
       unicode-character-names nil t))))
  (insert (cdr (assoc name unicode-character-alist))))

Yes, at least in Emacs 23 there is "C-x 8 RET" which let's you insert a
Unicode character by its name or code. Completion works in the
minibuffer so you don't need to remember character's name accurately.

don't think it is possible to insert a unicode char by its unicode
name. (Florian gave code for that i guess)

though, there are several ways to easily find and insert unicode chars
you want in emacs, by ascii markup, by your personal frequently used
char set, by particular lang's input methods, by code point, etc.

this page gives some detail.

• Emacs and Unicode Tips
  http://xahlee.org/emacs/emacs_n_unicode.html

i think it'd be useful for emacs to have some visual char map that
lets you select or view a category of chars for easy insertion.
(as in OS X's Character Pallette or Windows Character Map)
Shouldn't be diffucult to write one in elisp but as far as i know it
havn't been done.

C-x 8 RET gives the following prompt:

Unicode (name or hex):

And with fuzzy completion it is just great.
Thanks!
