Here the output of the ""file"" command: boost/math/special_functions/detail/bessel_i0.hpp: C++ source, Non-ISO extended-ASCII text boost/math/special_functions/detail/bessel_i1.hpp: C++ source, Non-ISO extended-ASCII text This makes the files incompatible with modern Microsoft Compilers when using switch /utf-8. The attached patch simply replaces the CP1252 dash with an ASCII dash and therefore fixes the issue for all compilers." Bugs closed To Be Determined math Boost 1.65.0 Problem obsolete
