This method supports UTF-8 encoding and is better suited for multilingual environments 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: Leverage internationalization extensions like Intl or external libraries (such as ICU) to perform more precise string handling based on language and region settings.

Conclusion

The ucwords() function is highly useful in single-language, English-dominant environments. However, in multilingual contexts, it is limited by character encoding and language rules. Developers seeking to ensure internationalization support should prioritize using mb_convert_case() or incorporate internationalization libraries.
