Braille Page Numbers

[GouldenJen]

Braille page numbers are particularly important for documents that will be produced in hard copy.

• Braille page numbers appear at the bottom right (last line) of a page (BANA).
• Braille page numbers appear at the top right (first line) of a page (UKAAF).
• The final digit of the number is in the last cell on the line.
• Some documents contain braille page numbers on every page.
• Some documents only contain braille page numbers on odd-numbered pages.
• There must be at least three spaces between the page number and any other text on the line.
• Transcriber-generated pages require a lower-case t immediately before the page number. (BANA)
• Front matter pages require a lower-case p immediately before the page number. (BANA)
• This issue needs more information re UKAAF and other braille authority requirements. How can CSS be used to ensure that braille page numbers appear in the correct location?

Braille page numbers cannot be taken from the original text (as the page size will vary from device to device. Therefore the reading system (RS) must be able to accurately generate braille numbers in a variety of formats, including, but not limited to:

• Arabic numbers, written using a set of ten appropriate braille characters (this covers Braille, Antoine, Nemeth etc), preceded by any required prefix.
• Roman numbers, preceded by any required prefix(es)
• Any other numbering scheme as needed - e.g. alphabetic.
• Or, omitted entirely
• Plus any requirements such as BANA prefix letters.
