A different approach for compile time emoji replacement

We can write preprocessor macros to define emojis like in this example

```cpp
#include
#define _admission_tickets_ u8"\\U0001F39F"

int main() {
const char *test = "Admission Tickets: " _admission_tickets_;
std::cout << test << std::endl;
return 0;
}
```

And on compilation, it expands to:
```
Admission Tickets: 🎟
```

Start by reviewing the repository's existing emoji replacement entry points and compile-time behavior; the issue does not name specific files or tests. Compare the proposed C++ preprocessor macro approach with the current implementation, and define completion as a working compile-time replacement that produces the expected emoji output.
