Thus, these high-ascii characters may not have a proper mapping, and a warning will be emitted by MSVC 2003 and 2005. This should be considered a failure case because, though low, it is still emitting an alert. Thus, without the correct region set on your system, the Boost sources fail to build. }}}" Support Requests closed Building Boost None Problem duplicate source character MSVC
