The latter is originally developed for the Mac port and it supports text shaping via Core Text layout engine in OS X. The mac-ct backend driver was incorporated for the NS port in Emacs 24.4. Below is the corresponding entry in etc/NEWS: * Changes in Emacs 24.4 on Non-Free Operating Systems ** New Core Text based font backend for Mac OS X 10.5 and newer. To use the old font backend, use the following on the command line: % defaults write org.gnu.Emacs FontBackend ns GNUstep and Mac OS X 10.4 use the old font backend. There was a bug in the composition string display code of the NS port (not in the font backend driver itself), and it is supposed to be fixed in the trunk: http://debbugs.gnu.org/cgi/bugreport.cgi?bug=3D20537 Actually, I couldn't reproduce the bug you described with the trunk. So, I think this is a duplicate of Bug#20537. YAMAMOTO Mitsuharu mituharu@math.s.chiba-u.ac.jp
