与cpp中的“世界”进行比较时，为什么会打印出“你好”？

我正在CPP中尝试模板。当我将其与“世界”进行比较时，我不明白为什么会打印“ Hello”？

以下是我的代码段->

#include <iostream>
using std::cout;
using std::endl;

template <typename T>
T max(T a, T b){
if(a > b){
return a;
}
else{return b;}
}

int main() {
  cout << "max(3, 5): " << max(3, 5) << endl;
  cout << "max('a', 'd'): " << max('a', 'd') << endl;
  cout << "max(\"Hello\", \"World\"): " << max("Hello", "World") << endl;
  return 0;
}

输出量

ec2-user:~/environment/cpp_learn/uiuc_cpp/cpp-templates (master) $ make
g++ -std=c++14 -O0 -pedantic -Wall  -Wfatal-errors -Wextra  -MMD -MP -g -c  main.cpp -o .objs/main.o
g++ .objs/main.o -std=c++14  -o main
ec2-user:~/environment/cpp_learn/uiuc_cpp/cpp-templates (master) $ ./main 
max(3, 5): 5
max('a', 'd'): d
max("Hello", "World"): Hello

这是我使用的C ++版本->

ec2-user:~/environment/cpp_learn/uiuc_cpp/cpp-templates (master) $ c++ --version
