I'm trying to display special unicode characters, in particular the mathematical operator in emacs. Specifically:
position: 283 of 317 (89%), column: 0
character: (displayed as ) (codepoint 120046, #o352356, #x1d4ee)
preferred charset: unicode (Unicode (ISO10646))
code point in charset: 0x1D4EE
syntax: w which means: word
category: .:Base, L:Left-to-right (strong)
buffer code: #xF0 #x9D #x93 #xAE
file code: #xF0 #x9D #x93 #xAE
(encoded by coding system utf-8-unix)
display: no font available
Unicode data:
Name: MATHEMATICAL BOLD SCRIPT SMALL E
Category: Letter, Lowercase
Combining class: Ll
Bidi category: Ll
Decomposition: font e
Character code properties: customize what to show
name: MATHEMATICAL BOLD SCRIPT SMALL E
general-category: Ll (Letter, Lowercase)
decomposition: (font 101) (font 'e')
There are text properties here:

I'm using GNU Emacs 24 a recent nightly binary. The text above displays fine on my browser and in TextEdit however, the special characters come up empty when viewed in emacs.
I read this from an old Emacs 22 manual: "A fontset does not necessarily specify a font for all character codes. If a fontset specifies no font for a certain character, or if it specifies a font that does not exist on your system, then it cannot display that character. It will display an empty box instead." - This is the exact behavior I am observing
It seems I may need to build a fontset to be able to display such arbitrary characters (starting with the Xdefaults or Xresources files).
How can I identify which font families I will need to include in the fontset to display Math operators (most online examples refer to languages li
