Luxembourgish Braille
It is very close to French Braille, but uses eight-dot cells, with the extra pair of dots at the bottom of each cell to indicate capitalization and accent marks.[1] The Luxembourgish Braille alphabet started off as a reduced set of the letters of the French Braille alphabet, the basic 26 plus three letters for print vowels with diacritics: ⠿ é, ⠫ ë, ⠜ ä.With the shift to eight-point script, these three acquired an extra dot at point 8.The exclamation mark is unusual, and brackets are in effect capitalized braces.[clarification needed] There are no capitalization or number signs in eight-dot Luxembourgish Braille.
