The character set for the Oberon/L CHAR data type is an 8-bit character set based on the ISO 8859-1 standard. It includes the ASCII (American Standard Code for Information Interchange) and the so-called Latin 1 extension to ASCII. Latin 1 includes most characters necessary for writing in languages which are based on Latin.
Both ASCII and Latin-1 contain slots for control characters, which are character codes used for various purposes, but which do not correspond to any visual representation of a character (a glyph).
In addition to ASCII and Latin 1, several punctuation marks from the 16-bit Unicode standard have been mapped into the upper (unused) control code portion of Latin 1.
The character set for the Oberon LONGCHAR data type is Unicode.
