I see this (huge cursor height and interline spacing) as well.

GNU Emacs 24.4.1 (i586-pc-linux-gnu, GTK+ Version 3.14.5)
 of 2015-03-08 on binet, modified by Debian

That's what (C-u C-x =) gives on the ∀:
             position: 842 of 1841 (46%), restriction: <131-1842>, column: 37
            character: ∀ (displayed as ∀) (codepoint 8704, #o21000, #x2200)
    preferred charset: unicode-bmp (Unicode Basic Multilingual Plane (U+0000..U+FFFF))
code point in charset: 0x2200
               script: symbol

            file code: #xE2 #x88 #x80 (encoded by coding system utf-8-emacs-unix)

On 𝔏 it gives:

            character: 𝔏 (displayed as 𝔏) (codepoint 120079, #o352417, #x1d50f)
