So, what about an arrow? In Nemeth, it begins with the shape indicator, so would it also need to be Nemeth or a tactile? I am sending an example of one along with the boxes. I see arrows in regular text simply meaning next step but could not find an example at the moment of this type.
Clarify for me the spacing for the colon used as "such that". An Introduction to Braille Mathematics Using Nemeth Code within UEB Contexts 6.7.16a states that a space would follow the colon in braille when used as "such that". I have looked to see if there is an update to remove the space following but I cannot find one.
My thought for the colon followed by an equal sign is putting these two symbols together without a space. The attached document shows the explanation from the text. I had wondered about putting the dot 5 between them to show they are horizontally.
I agree with you on the double-struck letters and will check through the book on that idea to see what is the best font to change to.
