It certainly need not affect performance of 'ordinary' text if the code is written properly. Paragrpah/Editor/etc have no need of paying any attention whatsoever to bidirectional languages - nor indeed to embedded shapes or any other oddities. >IF< you have a case where an embedded shape or variant display rules is needed then a suitable alternate class (maybe a subclass, maybe not) should be swapped in and then you are explicitly accepting the performance cost.
The potential performance improvement possible can be estimated by looking at how fast text display can be in MVC.
