This method supports UTF-8 encoding and is more suitable for multilingual scenarios than ucwords().

Custom Handling with Linguistic Rules: For complex languages, you can use regular expressions or custom logic to decide which words need capitalization and which should remain unchanged.

Use Internationalization Libraries: By utilizing internationalization extensions like Intl or external libraries (e.g., ICU), you can achieve more precise string handling based on language and region settings.

Conclusion

The ucwords() function is very useful in single-language environments, especially when English is the main language. However, in multilingual environments, it is limited by character encoding and language rules. Developers should prioritize using mb_convert_case() or internationalization libraries to ensure the application is friendly for global use.
