boost::locale::to_title() does not work

[Nathan Adams <nadams@…>]

The boost::locale::to_title() function appears to be broken.

This code:

int main( int argc, char* argv[] ) {

namespace bl = boost::locale;

bl::generator gen; std::locale loc( gen("en_US.UTF-8") ); std::locale::global(loc); cout.imbue(loc);

std::string temp("ALL UPPERCASE STRING"); temp = bl::to_title(temp,loc); cout << temp << endl; temp = bl::to_lower(temp,loc); cout << temp << endl;

return 0;

}

Outputs the following:

ALL UPPERCASE STRING all uppercase string

Have you compiled the Boost.Locale with ICU support?
