Localization: example from document page doesn't work for latin characters ?

[Jan Pfeifer]

hi again,

I was trying the example from the docs, for character transformation
(touppper/lower):

http://gcc.gnu.org/onlinedocs/libstdc++/22_locale/howto.html#7



But I noticed it doesn't work. From the example in the page -- see code
in the end of email --, I get the following transformations:

Órfão   (normal string, "orphan" in portuguese)
ÓRFãO  (should be upper case)
Órfão   (should be lower case)

Am I missing something, or is there something missing in the library ?

thanks!

jan

ps.: the source code:

#include <iostream>
#include <iterator>    // for back_inserter
#include <locale>
#include <string>
#include <algorithm>
#include <cctype>      // old <ctype.h>

using namespace std;

struct MyToUpper
{
    MyToUpper(std::locale const& l) : loc(l) {;}
    char operator() (char c) const  { return std::toupper(c,loc); }
    private:
        std::locale const& loc;
};
  
struct MyToLower
{
    MyToLower(std::locale const& l) : loc(l) {;}
    char operator() (char c) const  { return std::tolower(c,loc); }
    private:
        std::locale const& loc;
};


int main(int argc, char** argv)
{
    // locale loc( "" );
    // locale loc( "en_US.UTF-8" );
    locale loc( "pt_BR.UTF-8" );
    MyToUpper up( loc );
    MyToLower down( loc );
   
    string normal = "Órfão";
    cout << normal << endl;
    transform( normal.begin(), normal.end(), normal.begin(), up );
    cout << normal << endl;
    transform( normal.begin(), normal.end(), normal.begin(), down );
    cout << normal << endl;
   
   return 0;
}
