This is not a GNU FreeFont bug, but a Mac OS X 10.6 bug that will
affect certain characters of GNU FreeFont. Appearently, OS X 10.6 will
mess up the display of character that use nested references (character
A references to character B which in turn references to character C
which is drawn from scratch).
Two affected characters I've found are "quotedblleft" and
"quotedblbase" from freefont-ttf-20090104.tar.gz . The character
"quotedblleft" references to the character "quoteleft" which in turn
references to the character "quoteright" which is drawn from scratch.
The character "quotedblbase" references to the character
"quotesinglebase" which in turn references to the character
"quoteright" which is drawn from scratch.
For more wordy descriptions and screenshots, see:
The buggy OS X 10.6 behaviour can be prevented by replacing the nested
character references by single references (character A references to
character B which does not reference to any other character but is
drawn from scratch). Any nested reference can really be replaced by
Of course, there's nothing wrong with the GNU FreeFont nested
character references. If you would decide to remove the nested
references in a future release, it would only be as a courtesy to OS X
users who suffer from Apple's bug. You never know when Apple is going
to solve the bug.
