Alphabet
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 letters are thus: : Dot-7 is added to form capitals: : Apart from the accented letters, these are the letter forms of the Gardner–Salinas Braille code used for technical notation. The digits 1–9 (but not 0) are also as in Gardner–Salinas. However, Luxembourgish punctuation is quite different.Numbers
The Antoine notation being promoted in France is used for numbers. However, because there is no possibility of confusing these digits with the letters of the Luxembourgish alphabet, as there is with the French Braille alphabet, they are written without the French number sign . has been reassigned to the apostrophe. That is, in Luxembourgish Braille, numbers are simply written as they are in print, without requiring any special indication that they are numbers. :Punctuation
The exclamation mark is unusual, and brackets are in effect capitalized braces.Formatting
Formatting is used for emphasis and the like. There are no capitalization or number signs in eight-dot Luxembourgish Braille.References
