Re: ustring bug?

Hello,

Maybe you can try this approach:

~=~
//compile this with:
//gcc -g `pkg-config --cflags --libs glibmm-2.4` -o test test.cc
//assuming the filename is test.cc .

#include <locale.h>
#include <iostream>
#include <glibmm.h>

using namespace std ;

int
main (int argc, char **argv)
{
   //initialize the conversion functions correctly
   setlocale (LC_ALL, "") ;

   try {
       //convert a fixed char size string (where each char is 1 byte
long) into an utf8 string
       //(where each char can be between 1 and 4 bytes long)
       //using the conversion functions
       Glib::ustring utf8_str = Glib::locale_to_utf8 ("éçà") ;
   } catch (Glib::ConvertError &e) {
       cerr << "got converter error: " << e.what () << "\n";
       return -1 ;
   } catch (...) {
       cerr << "got an unknown error\n" ;
       return -1 ;
   }
   cout << "whoo, it works\n" ;
   return 0 ;
}
~=~

My locale is fr_FR euro  Maybe this works for you.

Do not forget to call setlocale (LC_ALL, "") to initialize the charset
conversion subsytem.

Also, I think ustring("foo") cannot work properly if "foo" is not a
valid utf8 sequence.
In your case, "foo" is not. So if "foo" is a string for which each
character can fit in one byte, you should rather put "foo" in a
std::string and convert it to a valid utf8 string using
Glib::locale_to_utf8() .

I hope this helps.

Cheers,

Dodji.
