Hello list, this is my first post to you :)

I've got a problem with handling locales and string_algo. 
As an example I want so make this string
        "hää?"
uppercase (->"HÄÄ?") by using this piece of code:

<code>
        #include <iostream>
        #include <locale>
        #include <string>
        #include <boost/algorithm/string.hpp>
        
        
        using namespace std;
        using namespace boost;
        
        int main(int argc, char** argv) {
        
            string loc_name = "de_DE.utf8";
        
            string str("hää?");
            str = to_upper_copy(str,locale(loc_name.c_str()));
        
            // ...should give "HÄÄ?"
            cout << str << endl;
            // but prints "Hää?"
        
            return 0;
        }
</code>

As you see I'm trying to use locales, but it doesn't work. What is my
mistake??

Thanks in advance, Maik

PS:
- I'm using gentoo-linux with gcc-4.1.1
- My locales list:
        LANG=de_DE.utf8
        LC_CTYPE="de_DE.utf8"
        LC_NUMERIC="de_DE.utf8"
        LC_TIME="de_DE.utf8"
        LC_COLLATE="de_DE.utf8"
        LC_MONETARY="de_DE.utf8"
        LC_MESSAGES="de_DE.utf8"
        LC_PAPER="de_DE.utf8"
        LC_NAME="de_DE.utf8"
        LC_ADDRESS="de_DE.utf8"
        LC_TELEPHONE="de_DE.utf8"
        LC_MEASUREMENT="de_DE.utf8"
        LC_IDENTIFICATION="de_DE.utf8"
        LC_ALL=de_DE.utf8
