Directions for the Translator to Braille 
Summary of Denotations: Character Conversion
Computer keyboards produce characters in a way that depends on the operating system and its configuration. To each character corresponds a code number that may be different from system to system.
To deal with texts coded in the most used systems, the translator converts some of the characters to its own unique representation. As this conversion is made before the phases of analysis and of output generation, it may happen that some error messages in those phases contain those representations instead of the original characters.
The following table describes the possible conversions. Its last column has the decimal code of the character and the encoding: ISO-8859-1 (latin1), ISO-8859-15 (latin9), Windows-1252 (cp1252). A missing encoding means that the code is the same in all of them. Texts in UTF-8 are first converted into ISO-8859-15 and then subject to this conversion.
