Itís a big wide world out there and we need to optimize usability for those factors for instance where a screen reader may be given a code for a minus sign which it reports out as xxxxxxyyyyyyyy.
So explaining this is a good things for authors to have.

Thanks for pointing this out.

1) As part of the "accessibility contract" authors must ensure that content is Perceivable and Understandable, thus this *is* an author issue (Sailesh feels otherwise).

2) There are multiple ways of visually rendering "a minus symbol" on screen, as Roger noted in his initial post:

I believe that it is important that authors understand which of those ways works versus which introduces confusion, etc.

I continue to believe that we, as authors, carry a slightly heavier lift in ensuring our clients are given the best user experience - this goes beyond just "letter of the law" accessibility, and into what is the Best Practice. (And lest anyone think I am being 'condescending' to non-sighted users here, I believe Best Practices for optimum user experience crosses all user-groups.)
