Boost version is 1_33_1, I think. When I compile a project that uses boost, I get the following warnings. C:\_Applied\AP.v10.0.3.3.Win32\asap\include\boost/lexical_cast.hpp : warning C4819: The file contains a character that cannot be represented in the current code page (932). Save the file in Unicode format to prevent data loss c:\_applied\ap.v10.0.3.3.win32\asap\include\boost/type_traits/is_base_and_derived.hpp : warning C4819: The file contains a character that cannot be represented in the current code page (932). Save the file in Unicode format to prevent data loss When I check the code, turns out that a guy named Terje Sletteb? (the letter after the b is garbage character in a Japanese OS) is using a special character that is not handled in a Japanese OS (code page 932). How can I get rid of this warnings? 1. save the boost files in Unicode 1200 using VS2010 2. can future boost library codes be saved in Unicode from the start? I wish you can do option2. Thank you, Atsushi " Bugs closed To Be Determined lexical_cast Boost Release Branch Problem fixed boost-1_33_1
