A Braille code is a code similar to a code page, that maps the characters of a writing system to the six, or in some cases eight, raised dots (or bits) of the Braille cell.

Different Braille codes are used to map character sets of different languages as well as for some special uses.

• Unified English Braille Code is an English Braille code.
• Japanese Braille encodes the Japanese hiragana character.
• Cantonese Braille is used for the Cantonese language in Hong Kong.
• Korean Braille encodes the Hangul alphabet of the Korean language.
• Braille music is used for representing musical notation.
• Nemeth Braille is used for representing mathematics.
• GS8 Braille uses eight-dot Braille cells for encoding mathematical and scientific notation.
