None of the above worked for me for emacs 24.5.1 on Debian Linux. So, after @siegebell made Fira Code Symbol font due to https://github.com/tonsky/FiraCode/issues/211 I spent several hours putting the following together which works for me:
```elisp
;;; Fira code
(set-fontset-font t '(#Xe100 . #Xe16f) "Fira Code Symbol")
(defconst fira-code-font-lock-keywords-alist
(mapcar (lambda (regex-char-pair)
`(,(car regex-char-pair)
(0 (prog1 ()
(compose-region (match-beginning 1)
(match-end 1)
;; The first argument to concat is a string containing a literal tab
,(concat " " (list (decode-char 'ucs (cadr regex-char-pair)))))))))
