 New locale library seems to have a bug.
 "Implemented generic codecvt facet and add general purpose utf8_codecvt
 facet"

 An exception occurs in boost 1.60 in Visual Studio 2013.
 "invalid multbyte/wide char conversion".

 This exception doesn't occur in boost 1.59, but this code makes invalid
 xml.
 The encoding is not UTF-8 but SJIS.

 In boost 1.57, it makes valid UTF-8 encoding xml.
