UEB Tech Question: Item within an item?

[Adrian Gregory]

I have a transformation that has a BD with a bidirectional arrow directly above it as a subscript to an r. (I have attached images of the print and the braille.) My question is, can I nest the braille grouping indicators as I have, or is there another way to do it? I need the entire BD with bidirectional arrow in grouping indicators to show it is all subscripted, but also need the BD in braille grouping indicators to show the arrow is above both letters and not just the D. Have I done this correctly? If not, please let me know how.

Thank you!

Thanks for your question, Adrian. And also a special thanks to Kyle for helping with the response while I was out of the office today; please see her response below.

Yes! I think you have “grouped” perfectly.

For a letter r that has the subscript “BD with a bidirectional arrow over both letters,” we need two sets of braille grouping indicators—one set encloses the full subscript (i.e., the letters and their modifier), and the other set of braille grouping indicators encloses the letters BD so that the bidirectional arrow is over both of them (not just the D).

ASCII of the braille under discussion:
;;r5<<,,bd>.9\wro>
