I am interested in finding the best way to include negative values in a
table. For example a table showing an overdrawn bank account or a
temperature below zero (c or f).


It seems that there is some variability in the level of screen reader
(and/or browser) support for coded &mdash; and &#8212; or the standard
keyboard dash.


One possibility would be to combine one of the above with the word 'minus'
which is positioned off-left so that it is not visible but will still be
read by a screen reader. However, this could result in some screen reader
users hearing "minus dash $40.00. Would this be worse than risking some just
hearing $40.00?
