Dr. Amina, a renowned linguist specializing in Arabic literature, is collaborating with Professor Dubois, a computer scientist, on a project to digitize a collection of ancient Arabic manuscripts. They aim to make the manuscripts accessible to a global audience by providing both the original Arabic text and a Latin transliteration. Dr. Amina insists on adhering strictly to the ISO 233:1984 standard for transliteration to ensure consistency and accuracy. One of the manuscripts contains numerous occurrences of the name \"سعيد\". Considering the nuances of the Arabic alphabet and the specific guidelines of ISO 233:1984 regarding the transliteration of Arabic characters, particularly the letters \"ع\" and long vowels, how should Dr. Amina correctly transliterate the name \"سعيد\" into Latin characters for the digitized manuscript? The correct transliteration must accurately represent the original Arabic pronunciation and conform to the ISO 233:1984 standard.
