But that's adaptation to ugly reality, _not_ compliance to standards, which
you say you're calling for. Besides, there's not much a screen reader _can_
do with layout tables other than processing them cell-wise and letting the
user specify the cell to be accessed, by row and column number, which is the
same as they need to do for a poorly-designed tabular data table.

No, we cannot. That's _not_ what they should do. There are several
international and national standards that say that ">" is GREATER THAN SIGN,
and this is certainly a correct and common use for it, no matter what we
think about other possible uses.
What would be, in your opinion, the correct reading for ">" in breadcrumbs?
Actually, it's difficult to figure out good wording. More importantly, the
results are catastrophic if the same words are used when a screen reader
presents, say, examples in an XML tutorial, or simple mathematical
expressions. If you are suggesting that screen readers should make
contextual analysis and then guess which words to use, I would say that you
are asking for too much; and they would be bound to guess wrong at times
(and IMHO rather often).

OK, I cite ISO 10646 and ISO 8859 (pick up any part thereof). Oh, and
ISO/IEC 15445. Your move.
