I investigated this a bit further and have a patch that fixes the
right-arrow test file for me, I can open it and the arrow displays without
problems.
Note that this is my very first foray into the Emacs source as well as into
Objective-C.
The problem is that ns_findfonts is being passed an empty font_spec. (Why,
I have no idea.) This crashes "[fdesc
matchingFontDescriptorsWithMandatoryKeys: fkeys]". The fix is to check for
this case and, if there are no keys in the font_spec, simply initialize
matchingDescs to an empty array.
Cheers,
Thomas
