The Manichaean block contains characters used in the Manichaean script, which was used to write the Manichaean texts of the Manichaeism religion, founded by the prophet Mani in the 3rd century CE. The script was used across a vast area from the Mediterranean to China, particularly for religious texts. This block includes characters for consonants, vowels, and punctuation marks, reflecting the historical significance of Manichaean texts and the spread of this once-prominent religion..
