Different fonts used for A for "Area" and A labeling a vertex

I'm transcribing precalculus material in UEB with Nemeth code.  Now that I've reached a section discussing finding the  area of triangles, they are using a different font to distinguish the A for Area from the A labeling a vertex.  I've attached a page where the special A for area is seen everywhere and the standard italicized A for the vertex can be seen on the first line under EXAMPLE 4 (triangle ABC).  Should I keep this distinction in braille?  And if so, how would you suggest I do that?  Italicize it?  Script A?

Thanks for your help!
