Save files with correct character set

[Spazzatura.Live <kharhonte hotmail com>]

Hi all!

I'm trying to save the content of a Glib::ustring to a file. I tried 
using the Glib::file_set_contents but it uses the std::string, and so it 
writes a non-unicode file. It works when i read it with Gedit (i think 
it recognize the right encoding), but with some other application, it 
doesn't! How can i solve this?
(Now I'm re-opening my files with Gedit and than save it with the right 
encoding before using)

Thanks.

Cheers,
Stefano
