     Type:  Bugs              |      Status:  new          
Milestone:  To Be Determined  |   Component:  property_tree
  Version:  Boost 1.41.0      |    Severity:  Regression   
 Keywords:                    |  
------------------------------+---------------------------------------------
 The following code works on GNU/Linux (g++ 4.2.4) but fails on Windows
 (XP/vc8) because the library function ''isspace'' called by the info-
 parser seems to include an additional check (i <= 255).

 {{{

 using namespace boost::property_tree ;
 wptree pt ;

 std::wfstream fs( "any_utf8_encoded_file.info" ) ;
 fs.imbue( std::locale( std::locale(), new boost::utf8_codecvt_facet ) );

 read_info( fs, pt ) ;
 }}}

 I replaced the call to the single-argument-version of ''isspace'' with the
 locale-aware version which results in a running solution but in
 consequence nearly every method in info_parser_read.hpp got as an
 additional parameter a reference to the stream. Maybe there is a more
 elegant solution.
