Thanks.

Emacs should not (and does not) insert directional controls into any
"usual" buffers, unless the user inserts them manually, or asks for
that in some other way.  These control characters can "leak" into such
buffers only if the user copy/pastes text from some "unusual" buffer.
But the same issue will happen if one pastes text with some other
non-ASCII character, like Cyrillic.
