ASCII and Latin-1 (ISO 8859-1) character sets
Oberon is based on the standard ASCII character set code points 00H to 7FH. The characters are produced with the respective labelled keys, including the use of Shift-key, on a US 101-key keyboard. For cross-platform portability, Oberon does not normally support all keys available on the keyboard.
The printable character or the function corresponding to a decimal code point can be generated by holding the Alt-key and keying the decimal value on the numeric keypad.
To find out a key's respective printable character and at the same time the decimal and the hexadecimal code point, execute EditKeys.GetKeyCode and follow the instructions in the System log. The command is documented in EditKeys.Tool .

Code points 80H to FFH
The assignment of special language characters to code points 80H to 95H is a property of the fonts delivered with Oberon. In HTML, any ISO Latin-1 character can be written as , where xxx is the decimal code point of the character, in place of the entity reference. Of the remaining code points, some are used by Oberon and others are unassigned. Latin-1 characters - ISO 8859-1 - can be produced on a US keyboard, as shown in the table below, using the Alt-key or a dead key stroke (the Shift key is implicitely required where A, O, U, " or ^ appear).
