Problems on Displaying some characters in a Gtk::TreeView

[Filipe Apostolo <f apostolo cbr gmail com>]

Hi to everybody,

Well I'm facing a strange problem when I try to display some special  character of the ascii table.

For example if I want to display character 3 of the table  (the heart) it will  not be displayed the heart . Instead it will be an Default symbol (I call it default because it appears in all unreconized symbols.

First I though that it was some conversion problem but then I tested and it is not that at all.

Well as an small example i done something  like this:

"Here I use std::string just to test all conversions".

std::string str;
char testeCh = 3;
str = testeCh;
std::cout << "STRING " << str << std::endl;
The output in the console window is the heart has I want.

Then I call a function that receives the  A Glib::ustring as parameter. And will set that parameter int the treeview with some others parameters.

mMyTreeview.InsertItemValue (itemRowIterator, timestampStr, str);

/////////////////////////////////////////
The Function is described here:

 void MyTreeView::InsertItemValue (const Gtk::TreeModel::iterator row_it,
                         const Glib::ustring &timestamp,
                         const Glib::ustring &value)
{
  Gtk::TreeModel::Row row = *row_it;

 std::cout << "USTRING: " << value << "; Ustring.c_str(): " << value.c_str () <<    std::endl;
   
row[mListColumnsModel.Value] = value.c_str();
  
 std::cout << "ROW Value: " << row[mListColumnsModel.Value] << std::endl;
  
 row[mListColumnsModel.Timestamp] = timestamp;  
}

The Output of Ustring and Row value in the console is the Heart symbol but in the Gtk::treeview value field is a strange symbol that appears in the other special ascii  symbols like the arrows, happy faces ond so one;

Could any one now what is missing in my code, or why is this appening
