ISO Latin-1 characters

Most of the ISO characters are implemented in OZ V4.5. However, due to constraints in the Blink hardware and the low resolution font map, there isn't space for them all. OZ V4.5 implements all the characters that are supported by the international keyboard layout, selectable via the Panel. The following table displays the complete ISO Latin-1 Ascii values and corresponding display characters, for reference:

Special characters
