Please read the documentation:

  "RapidXML does not fully support the XML standard; it is not capable
   of parsing DTDs and therefore cannot do full entity substitution.

   [...]

   Please note that RapidXML does not understand the encoding
   specification. If you pass it a character buffer, it assumes the data
   is already correctly encoded; if you pass it a filename, it will read
   the file using the character conversion of the locale you give it (or
   the global locale if you give it none). This means that, in order to
   parse a UTF-8-encoded XML file into a wptree, you have to supply an
   alternate locale, either directly or by replacing the global one."
