Sure, but that's a general issue in Emacs, so there are already
mechanisms in place to help deal with it
(e.g. yank-excluded-properties).
This one's different, believe me: no other text property changes the
_order_ of characters on display in creative ways. It could easily
render the text illegible, under just the right circumstances.
But isn't the "changed order" natural for the characters it's attached
to?
Only in the context of the kind of text (e.g., TeX) it was copied
from.
The copying may work if the feature is switched on for all buffers. The
reason for this is that things have to be reevaluated/fixed anyway every
time some buffer changes (e.g. insertion or deletion of a character)
happens. So if the text is copied to a buffer that doesn't do any
explicit reordering on top of the bidi algorithm, the special
overlays/properties/whatever will just be purged out.
On the other hand, it may also make sense to copy a piece of TeX *with*
the explicit TeX-specific reordering, because otherwise it may look like
garbage. Please remember that the goal of all these activities is to
make TeX or HTML/XML *legible*, because it's often illegible just with
the basic bidi algorithm.
Regards, Martin.
