ISO-8859-1, also known as Latin-1, is a standard character encoding that supports the majority of Western European languages. It includes characters from the English alphabet, along with accented letters and other special symbols commonly used in these languages. However, ISO-8859-1 does not include characters from non-Latin scripts such as Thai.

Thai language, being a non-Latin script, requires a different character encoding system to accurately represent its characters on computers and devices. UTF-8 (Unicode Transformation Format 8-bit) is one widely-used encoding scheme that supports Thai characters along with many other scripts. Unlike ISO-8859-1, which uses single-byte representation per character, UTF-8 utilizes variable-length encoding to accommodate a vast range of characters.

To ensure proper support for Thai keyboard inputs within an ISO-8859-1 encoded system, developers can consider implementing certain techniques. One approach is to use conversion functions or libraries that can transform Thai characters inputted through the keyboard into their corresponding Unicode representations before processing them. These Unicode representations can then be encoded using UTF-8 and stored or displayed appropriately.

Another option is to transition the entire system’s character encoding to UTF-8 instead of relying solely on ISO-8859-1. This would involve updating database schemas, file encodings, and any application logic related to text processing or rendering. By adopting UTF-8 as the standard encoding across the system, full support for Thai keyboards and other non-Latin scripts becomes achievable without limitations imposed by ISO-8859-1.

In conclusion, while ISO-8859-1 (Latin-1) has been useful for Western European languages, it lacks support for non-Latin scripts like Thai. Developers aiming to integrate Thai keyboard inputs into an ISO-8859-1 encoded system should consider employing techniques such as character conversion or transitioning to UTF-8 encoding. By doing so, they can ensure seamless communication and effective text representation for users with Thai keyboards, thus enhancing the overall user experience.
