Thoughts of the left-handed mastermind %uFFFD Apache 2 64K bug on Mac OS X 10.4 Tiger fixed: "For client version of Mac OS X Tiger (and for those who would like to compile Apache themselves on OS X Server as well) there's Apache version 2.0.55, which apparently includes a patch which fixes 64K bug as well. I've compiled and installed Apache 2.0.55 successfully on OS X Server 10.4.3 and 64K bug seems to be fixed."
