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-235 Braille pattern dots-235 The Braille pattern dots-235 ( ) is a 6-dot braille cell with dots raised, or an 8-dot braille cell with raised. It is represented by the Unicode code point U+2816, and in Braille ASCII with the number 6. In unified international braille, the braille pattern dots-235 is used to represent an exclamation point, other punctuation, and otherwise assigned as needed. † Abolished in Unified English Braille Related to Braille pattern dots-235 are Braille patterns 2357, 2358, and 23578, which are used in 8-dot braille systems, such as Gardner-Salinas and Luxembourgish Braille. In the Japanese kantenji braille, the
