Hello! This type of seemingly innocent problem has been something I have been struggling with. I would prefer not to use the numeric passage indicators, so that I can use contractions in the side comments. But then, for the omission boxes, I want to use the visible space symbols. Would I be able to use the visible space symbol for each omission in the spatial problem without a grade 1 indicator if it is not set off in numeric passage indicators? Thank you for your help.
We think it is alright to use the visible space symbol without any grade 1 indicators as long as it does not follow a letter.
If we use the one-cell visible space symbol instead of the box that print shows to indicate an omission, we should explain that change in a transcriber's note. For example, "The visible space symbol .=+ is used in braille where print has a box."
A possible transcription of item 1 from the print you shared is attached (as a picture and as a BRF).
