Thanks, now everything is clear.  Emacs composes the RIGHT-TO-LEFT
MARK (and other zero-width characters) with the next character, and
compositions don't yet work with bidi reordering.  The effect is
indeed duplication of characters.  You can see another example of this
problem in HELLO, in the Arabic and Hebrew lines -- they also use RLM.
