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-24 Braille pattern dots-24 The Braille pattern dots-24 ( ) is a 6-dot braille cell with the top right and middle left dots raised, or an 8-dot braille cell with the top right and upper-middle dots raised. It is represented by the Unicode code point U+280a, and in Braille ASCII with I. In unified international braille, the braille pattern dots-24 is used to represent unrounded, close or near-close, front vowel, such as /i/, /ɪ/, or /ɨ/. It is also used for the number 9. Related to Braille pattern dots-24 are Braille patterns 247, 248, and 2478, which are used in 8-dot
