Cross-platform single-header library to calculate the display width of UTF-8 strings. 

## Quick Start

```cpp

#include 

int main() {

    const std::string input = u8"Ｈｅｌｌｏ, ｗｏｒｌｄ!";

    

    // Calculate display width

    const auto result = unicode::display_width(input);

    

    // Verify result

    std::cout << "Input  : " << input << "\n";

    std::cout << "Output : " << std::string(result, '|') << "\n";

    std::cout << "Width  : " << result << "\n\n";

}

```
