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-14 Braille pattern dots-14 The Braille pattern dots-14 ( ) is a 6-dot or 8-dot braille cell with the two top dots raised. It is represented by the Unicode code point U+2809, and in Braille ASCII with "C". In unified international braille, the braille pattern dots-14 is used to represent unvoiced palatal fricatives or unvoiced alveolar affricates, such as /ts/, or /ç/, and is otherwise assigned as needed. It is also used to indicate the number 3. Related to Braille pattern dots-14 are Braille patterns 147, 148, and 1478, which are used in 8-dot braille systems, such as Gardner-Salinas and Luxembourgish
