Could this be solved with ligatures? I don't know about arabic,
but in latin text the sequence "ffi" is usually replaced with
a "ffi" ligature. (similar for fi, fl, ffl).  Some
fonts have even more ligatures.  A ligature character
usually looks like a "good" concatenation of the characters
that makes it, but this is not a requirement.

Note that ligatures is a font property, so it don't need any
extra support from lyx.  Well, perhaps it is necessary
for displaying on screen, but not for printing or print previewing.
