After the Mac port font backend was ported to the trunk, there appeared a new display problem with LaTeX files on macosx. When I open a file in latex mode and enter $x_0^0$, both 0s are shown in superscript position, whereasthe first 0 should be in subscript position. Also, when using AUCTeX, all the section, subsection, etc. arguments are shown in subscript position. A recipe to reproduce the problem from emacs -Q: open a file "test.tex" and enter $x_0^0$. When I comment out these lines (starting on line 1178) in nsfns.m: #ifdef NS_IMPL_COCOA #if MAC_OS_X_VERSION_MAX_ALLOWED >=3D MAC_OS_X_VERSION_10_5 if (CTGetCoreTextVersion !=3D NULL && CTGetCoreTextVersion () >=3D kCTVersionNumber10_5) mac_register_font_driver (f); #endif #endif and recompile, the LaTeX code is displayed correctly again. Can you reproduce this problem? I use clang version 500.2.75 from xcode 5 and osx 10.8.5. I don't know what the above code does, but I hope it helps finding the cause of the problem. I was advised by Jan Djärv that setting the font-backend frame parameter to "ns" also corrects the display problem. Many thanks.
