   Due to the implementation, this minor mode will probably break your
   input method.  If you do not know what an input method is or if you
  -only write in English or in other European languages, chances are you
  -are not using one.

positive.code: = LaTeX-unicode-math-mode
  
  This is an emacs minor mode for entering unicode math symbols in
  LaTeX.  It automatically replaces inputs like `\phi` with `φ` and
  `\in` with `∈`.  These replacements happen inside of math environments
  or everywhere, depending on the configuration.
  
  You probably want `\usepackage{unicode-math-mode}` to make LaTeX aware
  of the unicode characters.
  
  Add this to your emacs configuration somewhere *after* loading auctex:

negative.code: (add-hook 'LaTeX-mode-hook 'LaTeX-unicode-math-mode)
  
  ;; Enable LaTeX-unicode-global-mode automatically for all LaTeX files.
  ;; This converts LaTeX to unicode everwhere, not only in math
  ;; environments.
  ;;(add-hook 'LaTeX-mode-hook 'LaTeX-unicode-global-mode)

  Note that `LaTeX-unicode-math-mode` and `LaTeX-unicode-global-mode`
  are mutually exclusive.  Only one of them can be active for one
  buffer.
  
  Tested with pdflatex from TeX Live 2015 and GNU Emacs 24.5.1.
