Braille
More differences are in Chinese braille. In Mandarin Braille, which is based on Zhuyin rather than the Latin Pinyin alphabet, the Latin braille values are used for the first consonants and the simple vowels. There are additional blocks for the tones, diphthongs, and any following vowel + consonant combinations. Cantonese Braille is also based on Latin braille for many of the initial consonants and simple vowels, but the blocks also have different values depending on whether they are in a leading syllable or following syllable position. For instance, the block for Latin k represents old-style Cantonese k (g in Yale and other modern Romanizations) when initial, but aak when final, while Latin j represents Cantonese initial j but final oei.
