The Vai block includes characters used in the Vai script, which is used to write the Vai language spoken in Liberia and Sierra Leone. The Vai script is a syllabary, where each character represents a syllable rather than an individual phoneme. The script was developed in the early 19th century by Momolu Duwalu Bukele, who was inspired by a dream to create a writing system for his people. The Vai script is still in use today, particularly for writing religious texts, personal letters, and cultural documents. This block includes characters for all the syllables used in the Vai language, as well as a few additional marks for punctuation..
