How to check if path is valid in boost::filesystem?

问题

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.
