This language is usually produced in uncontracted braille, which means that words in the text are rendered in braille on a one-for-one basis: one braille character for each inkprint letter. Some inkprint punctuation may require more than one braille character. Indicating upper case, emphasis, or numbers also adds braille characters to the character count. However, the braille contains no abbreviations or contractions.
If you have questions about producing correct braille, please contact a member of the appropriate braille authority.
