I am setting a boost::filesystem::path from an edit field. I notice that the constructor is happy to accept invalid characters for the filename.
How can I use boost::filesystem to check if the boost::filesystem::path object represents a valid filename?
Have a look here:
http://www.boost.org/doc/libs/release/libs/filesystem/doc/portability_guide.htm
This describes various functions for checking whether filenames are valid or not.
