the best way i found to replace is simply copy & paste the char in
To find out what that char is, you can do “Ctrl+u Ctrl+x =”. It'll
give you the full unicode name, code number, and all sort of info. But
you have to intsall the unicode file... See:
Q: I have this character α on the screen. How to find out its
unicode's hex value or name?
You can find out a character's decimal, octal, or hex values by
placing your cursor on the character, and type “Alt+x what-cursor-
position” (Ctrl+x =). You can get more info if you place your cursor
on the character, then press “Ctrl+u Ctrl+x =”.
However, if you want the complete unicode info of a character, you
need to download a unicode data file and let emacs know where it is.
The unicode data file can be downloaded at:
After you downloaded it, place the following code in your “~/.emacs”
to let emacs know where it is:
; set unicode data file location. (used by what-cursor-position)
(let ((x "~/Documents/emacs/UnicodeData.txt"))
(when (file-exists-p x)
(setq describe-char-unicodedata-file x)))
Then restart emacs. Once you've done this, then place your cursor on a
unicode char, and do “Ctrl+u Ctrl+x =”, then emacs will give you all
the unicode info about that char, including the code point in decimal,
octal, hex notations, as well the unicode character name, category,
the font emacs is using, and others.
For example, here's the output on the character “α”:
character: α (332721, #o1211661, #x513b1, U+03B1)
(Unicode characters of the range U+0100..U+24FF.)
code point: #x27 #x31
syntax: w which means: word
buffer code: #x9C #xF4 #xA7 #xB1
file code: #xCE #xB1 (encoded by coding system mule-utf-8-unix)
display: by this font (glyph code)
Name: GREEK SMALL LETTER ALPHA
Category: lowercase letter
Combining class: Spacing
Bidi category: Left-to-Right
