There was a Malaccan warrior called Hang Tuah. Thought it was claimed by a professor that that is not real name but Hang Tuha, and Tuha is related tu Tua means old. He said people called Tuah because researchers failed to read this old Jawi spelling توه. This is abjad writing derived from Arabic, and it can be read as tuha, tuah and toh, because at a certain time Malay people stopped using arabic diacritics, so it will cause confusion and made homograph.
