Subject: [PATCH] Let's hope that the std::exception::what() returns either a
 7-bit string or an UTF-8 string. Let's convert it to wxString before showing
 an error message box. boost::system shall return UTF-8 localized error
 messages as long as we set -DBOOST_SYSTEM_USE_UTF8 in the top most
 CMakeFiles.txt, which we do.
