Unable to extract Unicode symbols from C++ std::string
问题 I am looking to read a C++ std::string, then passing that std::string to a function which would analyse it, then extract Unicode symbols & simple ASCII symbols from it. I searched many tutorials online, but all of them mentioned that standard C++ does not fully support Unicode format. Many of them mentioned to use ICU C++ . This is my C++ program for understanding the very basic of above functionalities. It reads the raw string, converts to ICU Unicode String & prints that: #include <iostream
