That should work. There's also a global function: c_to_eu_string(p)
which takes a pointer to a null-terminated string, which GTK returns,
and produces a Euphoria sequence.

So you could replace the above with:

printf(1,"%s",{c_to_eu_string(get_text(txt))}) 

I have updated the get_text() function to automatically do the  
conversion, and will post the new version to my website later today.
