You can set at least (to basic_file_source
http://www.boost.org/doc/libs/1_35_0/libs/iostreams/doc/classes/file.html#file_source)
that it should be opened in the binary mode.

I think you can pass any of the flags defined in std::ios_base::openmode. If
that does not work, try to unset skipws flag, which skips all white spaces
when reading stream, but that actually should not apply to binary stream at
all.

Best Regards,
Ovanes.
