Hi,
Based on the answers which clearly stated that it would not work with delay loading the UTF DLL I tried to modify the Boost UTF implementation to get it working.
The code you see below is probably not following the Boost guidelines but it made it possible for us to use the UTF with delay loading of the UTF dll.
