UNICODE.txt

To insert unicode characters into emacs, you can set the TeX input
method by typing `C-u C-\` (or `M-x set-input-method RET`), typing
`TeX`, and pressing RETURN.  You can then insert characters as you
would in TeX, such as `•` by typing `\bullet`.  There are other
unicode input methods, as well.  For example, if you have Agda
installed, you can enter `Agda` as the input method, and then you can
enter `•` by typing `\bu`.

Emacs can tell you how to enter a pre-existing character: place the
cursor right before the character, and type `C-u C-x =` (or `M-x
describe-char RET`).

To default to TeX input method when editing Coq files, add the
following to your ~/.emacs:

(defun my-coq-hook ()
  (set-input-method "TeX"))

(add-hook 'coq-mode-hook 'my-coq-hook)


Instructions for entering unicode into CoqIDE are documented in the
Coq Reference Manual (http://coq.inria.fr/refman/toc.html).  You can
find the v8.4 documentation about unicode input at
