Also reformat the code to follow wx style and explicitly use UTF-8 for the test strings encoding instead of assuming the encoding of the current locale was UTF-8 (which is never the case under Windows). git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@63685 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
