How to get decimal value of a unicode character in c++

问题

For one of my opensource projects, i need to compute the decimal equivalent of a given unicode character.

For example if tamil character L'அ' is given, the output should be 2949 .

I am using c++ in Qt environment. I googled and could not find a solution for this. Please help if you know a solution for this.

回答1:

Use the unicode() method of the QChar object (which you can get e.g. with the at method of a QString, if a QString is what you have to start with).

回答2:

cout << (int)c 

that's it

回答3:

void print_decimal(wchar_t character)
{
  std::cout << int(character);
}
