Morse code thus determines the dot length. It is common to assume that a word is 5 characters long. There are two common typical words: "PARIS" and "CODEX". PARIS mimics a word rate that is typical of natural language words and reflects the benefits of Morse code's shorter code durations for common characters such as "e" and "t". CODEX offers a word rate that is typical of 5-letter code groups (sequences of random letters). Using the word PARIS as a standard, the number of dot units is 50 and a simple calculation shows that the dot length at 20 words per minute
Braille pattern dots-2 Braille pattern dots-2 The Braille pattern dots-2 ( ) is a 6-dot braille cell with the middle-left dot raised, or an 8-dot braille cell with its mid-high left dot raised. It is represented by the Unicode code point U+2802, and in Braille ASCII with the number "1". In unified international braille, the braille pattern dots-2 is used to represent a comma or other non-letter symbol or semi-letter. Related to Braille pattern dots-2 are Braille patterns 27, 28, and 278, which are used in 8-dot braille systems, such as Gardner-Salinas and Luxembourgish Braille. In the Japanese kantenji braille, the standard 8-dot
