Gnome VFS and GtkTextBuffer, character encodings?

[Micah Carrick <email micahcarrick com>]

I'm still wet behind the ears hear so bare with me.  I'm trying to load 
a text file into a GtkTextBuffer.  When doing so with local text files, 
no problem.  However, when I open a file that I created on my Windows 
system, the program crashes due to utf8 validation.  So used 
g_utf8_validate() to catch this.  However, I need to be able to read 
this type of file (it's a text file containing assembly code).  I'm 
using something like the following to read the file (using gnome-vfs):
  

do {

   result = gnome_vfs_read (handle, 

           text_buffer,

           BUFFER_SIZE, 

           &bytes_read);

   

   bytes_total += bytes_read;

} while(result == GNOME_VFS_OK);

if(result == GNOME_VFS_ERROR_EOF) {

   text_buffer = g_strconcat("", NULL);

   

}


Is there some easy way to determine the character coding of the file I'm 
opening and make a conversion before trying to put it into a GtkTextBuffer?
