For all its > derivatives. No, because programming-language modes include strings and comments, where the correct rendering is important. This variable should not be set non-nil unless the display engine is abysmally slow. In all other cases doing so is giving up correct display while gaining nothing, because in "sensible" buffers the BPA implementation is fast enough. > I think in all of these cases we're unlikely to see bidirectional text. I don't think "unlikely" is a good enough reason to do what you suggest by default. Emacs by default should produce correct display of all scripts it supports, even in unlikely use cases. Please don't make me regret I added this variable (or the bidi display in general).
