There's another side to the entire BiDi story, though. Simple utilities like "echo", "cat", "ls", "grep" and so on, line editing experience of your shell, these kinds. It's absolutely not feasible to add BiDi support to these utilities. Here the only viable approach is to have the terminal emulator do it.
How will "ls -l" possibly work? This is an example of the "table" layout you were already discussing.
I think us command-line troglodytes just have to deal with not having a whole lot of BiDi support. There's simply no way any terminal emulator could possibly know what makes sense and what doesn't for a given line of text, coming from some random program. Your "grep" could be grepping from a file with ANY layout, not necessarily one conducive to terminal layout, and so on.
