I'm having a lot of difficulty in finding an explicit explanation of how to use the "Mathematica Fraktur", as defined in the top answer of this post: What are all the font styles I can use in math mode?
I suppose then my question is:
How, when using $\mathfrak{A}$, do I get the output to be the letter A, but in the font "Mathematica Fraktur", without changing the font of my entire document?
