issue: can't customize font

[dustinfarris]

This is not working for me:

(custom-set-faces
  '(claude-code-repl-face ((t (:family "JuliaMono")))))

Both eat and vterm seem to ignore this. The only way I've been able to customize the font is via claude-code-start-hook:

(defun df/set-julia-tiny ()
  "Set JuliaMono :height 0.8 for the current buffer."
  (buffer-face-set '(:family "JuliaMono" :height 0.8)))

(add-hook 'claude-code-start-hook #'df/set-julia-tiny)

Hmm can you share a stripped down version of your init.el? This works for me:

(custom-set-faces
   '(claude-code-repl-face ((t (:family "JuliaMono" :height 0.8)))))

describe-char shows:

    mac-ct:-*-JuliaMono-light-normal-normal-*-11-*-*-*-m-0-iso10646-1 (#x2DA)

(My normal font is height 14 and Maple Mono).

This is what I have (more or less)

(defun df/set-julia-tiny ()
  "Set JuliaMono :height 0.8 for the current buffer."
  (buffer-face-set '(:family "JuliaMono" :height 0.8)))

  "Set SF Mono for the current buffer."
  (buffer-face-set '(:family "SF Mono" :height 0.9)))

(defun df/set-sfmono-1.3 ()

  (buffer-face-set '(:family "SFMono 1.3" :height 1.1)))
