Fred,
It is difficult. If we do go down the rabbit hole of designing a non-spatial transcription of the printed horizontal curly brace, then I suspect we must make it very clear what the printed braces are "embracing." That would be "x-squared equals thirty-six" and "x equals six or x equals minus six" In addition, it is probably not best practice to insert an opening curly brace in braille when only the closing curly brace is shown in print.
Thus, I think the following is what we would have to do:
,IF
;;<X9#B "7 #CF>.5<;',HYPO!SIS_>1 !N
;<X "7 #F OR ;X "7 "-#F>.5<;',3CLU.N_>where braille grouping indicators enclose the "embraced" material and a directly below indicator precedes the "pointed to" material, which is enclosed with an opening braille grouping indicator and a closing curly brace.
Whew. I prefer the spatial approach. What do you think?

Corrected versions of all my examples are attached.
No worries!
A tactile graphic would likely be the most reader-friendly solution. However, since that is not always possible, you could use line mode to create something like the attached (in image and braille file formats).
Thank you for the question!
–Kyle & the UEB Technical Material Committee
Yes, I see why this is challenging. Can you please confirm that the attached image roughly corresponds to your print?
I must change my response!
In fact, the numeric-mode-initiated grade 1 is terminated by a line break. See the clarification of this rule in #5 of the "Provisional Guidance on Transcribing Mathematics in UEB" (quoted below).
Note that, in the case of an expression that is divided over more than one line, the end of a braille line counts as a braille space unless the dot 5 continuation indicator is used.
Nonetheless, a line continuation indicator (dot 5) is not most appropriate here, because it is clear that your runover line is a continuation of the expression that started on the previous line. To use a dot 5 continuation indicator would be overkill and probably confusing for the braille reader.
So, for the print in your first post, I would now recommend the following transcription as being the most accurate and easy-to-read.

. Reason: make double quotes in example braille cells and not print quotation marks

Clara,
I am not confident I can formulate an answer to this question.
First, please let me make sure that I understand the situation. You're transcribing mathematical material that is written in Spanish? You're using uncontracted UEB (including UEB modifers (aka accents), UEB punctuation, and UEB typeform indicators) for the narrative text? And you're using Nemeth Code (surrounded by code switch indicators) for the mathematical material? [And the reader is familiar with this code combination?]
Second, please let me make sure I know what you are asking. Are you asking about letters that are standing alone in the narrative text (i.e., in UEB)? And, are you not asking about single-letters within Nemeth Code (i.e., inside Nemeth Code switch indicators)?
Thank you for clarifying!
–KyleSusan, could you please attach a .BRF? (.DXB files cannot currently be uploaded to Ask an Expert.)
Thank you.
–KyleThe image you shared is of a letter R in the “double struck” or “blackboard bold” print typeface. This is commonly used for letters that refer to sets of numbers (e.g. ℝ for real numbers, ℤ for integers, ℕ for natural numbers).
11.6 of the UEB Guidelines for Technical Material says, "Embellished capital letters are often used to name common sets such as the universal set E, the set of real numbers R or integers I. These vary in print from book to book but can be represented in braille by the script typeform indicators."
You are correct that we should use the script typeform for your example, and the appropriate transcription is ⠈⠆⠰⠠⠗ ("script symbol indicator grade 1 symbol indicator capital R")
Thank you for asking!
–KyleYou do not need a dot 5, because it is clear that your runover line is a continuation of the expression that started on the previous line. A dot 5 continuation indicator is only necessary "in the unlikely case where the two portions [of an expression] could be read as two separate expressions" as the Guidelines for Technical Material say (1.4.3).

With or without a continuation indicator, you do *not* need a grade 1 indicator in your runover line. In both of the items you included as attachments, the grade 1 mode established by a numeric indicator continues across a braille line break (again, with or without a continuation indicator this is true).
Thank you for asking a clarifying question.

LaVerne,

That is well summarized question: Is a runover line considered a "space?" The answer is no. As illustrated in the first long numeral example on page 60 of the Rules of UEB, transition to a new braille line does not terminate the effects of a numeric indicator. In other words, the numeric mode and the grade 1 mode established by a numeric indicator continue through a braille line break. They survive being run over!
Thank you for the question.

Susan,
For number lines, which are a way of representing spatially the relationships between numbers, a tactile graphic (or raised line drawing) is best.
Since both we and the Guidelines for Technical Material exist in the real world, where tactile graphics can be prohibitively expensive and time-consuming, tactile graphics are NOT THE ONLY way to transcribe a number line. We could use line mode to "draw" number lines with braille cells, as long as we're careful to use the appropriate indicators (arrow mode, line modes, numeric indicators, etc.) so that the braille reader is alterted when something represents a line to be "traced" and not a symbols-sequence to be "read." Nonetheless, it is BETTER TO DRAW number lines 99% of the time, including your examples.
Does that address your concern?
–Kyle
