Nigerian braille

Several braille alphabets are used in Nigeria. For English, Unified English Braille has been adopted. Three other languages have been written in braille: Hausa, Igbo, and Yoruba. All three alphabets are based on English readings, with the addition of letters particular to these languages. Punctuation is as in English Braille.
