 Hi,
 The example in that link works fine for narrow char. I am using wide char
 header line. But I can not find the wide char version of
 text_file_backend::stream_type. Which one shall I use? Thank you.

 Your example:
 {{{
 void write_header(sinks::text_file_backend::stream_type& file)
 {
     file << "<?xml version=\"1.0\"?>\n<log>\n";
 }
 ...

 sink->locked_backend()->set_open_handler(&write_header);
 }}}
