Symbols:Fonts/mathscr/Lowercase

Font Description
The lowercase letters of the alphabet rendered in the mathscr font are:
 * $\mathscr {a \ b \ c \ d \ e \ f \ g \ h \ i \ j \ k \ l \ m \ n \ o \ p \ q \ r \ s \ t \ u \ v \ w \ x \ y \ z}$

Hence the lowercase letters are not implemented in mathscr, the presentation defaulting to mathrm.
