Applying this backported patch from upstream fixes the following test failure:
* Detail of EscapeSequenceTest/writeEscapeSequence test failure: /home/viktor/jsoncpp/src/test_lib_json/main.cpp(3370): expected == result Expected: '["\"","\\","\b","\f","\n","\r","\t","\u0278","\ud852\udf62"] ' Actual : '["\"","\\","\b","\f","\n","\r","\t","ɸ","𤭢"] ' This failure only happens on architectures that use unsigned char as default type for char. It doesn't happen on x86 because it uses signed char by default. However, the failure can be emulated on x86 by adding the following line to the beginning of CMakeLists.txt: add_compile_options(-funsigned-char) Also, there is another bug in the code that is fixed by this upstream patch: "static_cast<unsigned char>(*cur) < 0x80" should be: "static_cast<unsigned char>(*cur) >= 0x80" This patch is not needed in master or gatesgarth branches, because they use version 1.9.3 of jsoncpp, which doesn't have the bug.
