Emacs 24.4.1中的下标未正确显示

Question

我正在进行使用unicode下标k("\ _k")的赋值.但是,我没有得到下标k,而是得到了这个:

![] [1]

仍然可以使用带有数字和一些字母的下标,但不能使用'k'.

我最初遇到了emacs 24.3的问题,然后被告知更新到24.4.这个问题仍然存在.

有没有其他人有这个问题,并找到了解决方案？

我在使用Emacs v.24.4.1的Mac上运行

提前致谢

这是我的.emacs文件:

(load-file (let ((coding-system-for-read 'utf-8))
             (shell-command-to-string "agda-mode locate")))

(set-default-font "-apple-DejaVu_Sans-medium-normal-normal-*-*-*-*-*-p-0-iso10646-1")
; Change Control-c Control-, and Control-c Control-. in Agda mode
; so they show the normalized rather than the "simplified" goals
(defun agda2-normalized-goal-and-context ()
  (interactive)
  (agda2-goal-and-context '(3)))
(defun agda2-normalized-goal-and-context-and-inferred ()
  (interactive)
  (agda2-goal-and-context-and-inferred '(3)))
(eval-after-load "agda2-mode"
  '(progn
     (define-key agda2-mode-map (kbd "C-c C-,")
       'agda2-normalized-goal-and-context)
     (define-key agda2-mode-map (kbd "C-c C-.")
       'agda2-normalized-goal-and-context-and-inferred)))

; This defines backslash commands for some extra symbols.
(eval-after-load "quail/latin-ltx"
  '(mapc (lambda (pair)
           (quail-defrule (car pair) (cadr pair) "TeX"))
         '( ("\\bb" "") ("\\bl" "") ("\\bs" "")
            ("\\bt" "") ("\\bv" "") ("\\cv" "?")
            ("\\comp" "?") ("\\m" "?") ("\\om" "?"))))

; This sets the Control-c Control-k shortcut to
; describe the character under your cursor.
(global-set-key "\C-c\C-k" 'describe-char)

(custom-set-variables
 '(agda2-include-dirs
   (quote ("." "/Users/dylanthiemann/Dropbox/University of Iowa/2nd Senior Year/Spring 2015/PLC/ial")))
 )

代码来自Agda:

module bool-kleene-thms where

open import bool
open import bool-kleene
open import eq

&&?-idem : ? (b : ?) ? b &&? b ? b
&&?-idem b = {!!}

tt-&&? : ? (b : ?) ? tt &&? b ? b
tt-&&? b = {!!}

||?-idem : ? (b : ?) ? b ||? b ? b
||?-idem b = {!!}

||?-tt : ? (b : ?) ? b ||? tt ? tt
||?-tt b = {!!}

||?-ff : ? (b : ?) ? b ||? ff ? b
||?-ff b = {!!}
