I am also finding an underscore in my work with a statistics book. The underscore appears in variables expressed as words, and seems to be used as a connecting hyphen would be used but since a hyphen looks like a minus sign, the underscore is being used instead. I have attached a sample where 16_21 means "sixteen through twenty-one." How can I braille an underscore in this context?
