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-236 Braille pattern dots-236 The Braille pattern dots-236 ( ) is a 6-dot braille cell with the middle left and both bottom dots raised, or an 8-dot braille cell with the upper-middle left and both lower-middle dots raised. It is represented by the Unicode code point U+2826, and in Braille ASCII with the number 8. In unified international braille, the braille pattern dots-236 is used to represent various punctuation, often coupled with Braille pattern dots-356 as an opening mark. Related to Braille pattern dots-236 are Braille patterns 2367, 2368, and 23678, which are used in 8-dot braille systems, such as Gardner-Salinas
