 Please remove the unnecessary non-ascii character located just after the
 sceond single quotation mark at line 34 of
 boost/type_traits/detail/has_binary_operator.hpp. This causes a compiler
 warning as indicated below.

 > boost\type_traits\detail\has_binary_operator.hpp:
 >     (line 34) Non-ASCII: //    warning C4547: '*'Â : operator before
 comma has no effect; expected operator with side-effec


 Following is the one I got in Visual Studio 2008 on Japanese Windows:

 E:\App\boost_1_49_0\boost/type_traits/detail/has_binary_operator.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


 The funny thing is that this comment is warning another compiler warning
 :)


 {{{
