I have a problem with the functions in the string_algo package.
Consider this piece of code:
#include <boost/algorithm/string.hpp>
int main() {
try{
string s = "meißen";
locale l("de_DE.UTF-8");
to_upper(s, l);
cout << s << endl;
catch(std::runtime_error& e){
cerr << e.what() << endl;
}
try{
string s = "composición";
locale l("es_CO.UTF-8");
to_upper(s, l);
cout << s << endl;
catch(std::runtime_error& e){
cerr << e.what() << endl;
}
}
The expected output for this code would be:
MEISSEN
COMPOSICIÓN
however the only thing I get is
MEIßEN
COMPOSICIóN
so, clearly the locale is not being taken into account. I even try to set the global locale with no success. What can I do?

In addition to the answer of Éric Malenfant --
std::locale
facets works on single character. To get better result you may usestd::wstring
-- thus more characters would be converterd, but as you can see it is still not perfect (example ß).I would suggest to give a try to Boost.Locale (new library for boost, not yet in boost), that does stuff
http://cppcms.sourceforge.net/boost_locale/docs/,
Especially see http://cppcms.sourceforge.net/boost_locale/docs/index.html#conversions that deals with the problem you are talking about.
