Convert a String In C++ To Upper Case

Question

How could one convert a string to upper case. The examples I have found from googling only have to deal with chars.

Answer 1

Using Boost.Text, which will work for Unicode text

boost::text::text t = "Hello World";
boost::text::text uppered;
boost::text::to_title(t, std::inserter(uppered, uppered.end()));
std::string newstr = uppered.extract();
