Re: properties for exposing custom Braille descriptions

Braille ASCII varies between countries, hence between the braille tables loaded by screen readers – so it can’t be used to specify a desired braille representation reliably.

For example, if the author assumes North American ASCII braille, but the user’s system is configured for one of the European codes, the result won’t be what the author would expect.

Only the Unicode block is unambiguous.

Hi Jason,

This question is mentiond in the list of questions at the end of the page. My apologies if the page was not accessible enough to make it there.

Speaking for myself, I'd very much hope that Unicode Braille would work. But Braille ascii might be a useful consideration. As I understand it, NVDA's prototype back in May pushed the raw value out (and Sina's test files used grade 1).

Best regards,
Peter.
