Copying from my SO answer <http://stackoverflow.com/q/24422449/341065>:

Since log4cplus 1.1.0-RC10 you can specify locale to be imbued into
|std::filestream| used by file appenders. See FileAppender documentation
<http://log4cplus.sourceforge.net/docs/html/classlog4cplus_1_1FileAppender.html>,
especially the |Locale| property. In your case, try to imbue it with
|en_US.UTF-8|.
