The Boost Exception framework itself doesn't set a limitation on what you can stuff in exceptions. You can use something like:

typedef boost::error_info wfile_name;

and then you can stuff it in and recover it from exceptions just fine. The only issue is how boost::diagnostic_information (which returns a std::string) will display a wfile_name, and I'm sure whatever it does now isn't correct.

So this isn't a trivial problem. Perhaps the correct thing to do is document that boost::diagnostic_information returns a UTF-8 string, I kind of prefer this to the other possibility, to add a boost::wdiagnostic_information.

What about:  - having boost::diagnostic_informationreturn a UTF-8 encoded string for all error_info containing a std::wstring

What is difference between that and just documenting that boost::diagnostic_information returns a UTF-8 string *always*?

 - adding a boost::wdiagnostic_information

If boost::diagnostic_information returns a UTF-8 string, boost::wdiagnostic_information is a trivial wrapper. Emil Dotchevski Reverge Studios, Inc. http://www.revergestudios.com/reblog/index.php?n=ReCode
