The Acorn RISC OS character set was used in
the Acorn Archimedes series and subsequent
computers from 1987 onwards.
It is an extension of ISO/IEC 8859-1.
== Code page layout (standard) ==
Characters at 0x83, 0x84, 0x87, 0x88, 0x89,
0x8A, and 0x8B are specific to the Acorn RISC
OS and therefore, are not in Unicode.
At 0x83 is a box with another box inside it
on the top left-hand corner, meaning "resize
window".
At 0x84 is a A 'bubble-writing' X, meaning
"close window".
At 0x87 is a very strange character that is
an 7-segment-styled 8 with an 7-segment-styled
7 to the top right of it.
At 0x88, 0x89, 0x8A, and 0x8B are left, right,
up, and down bubble arrows for window scrollbars.
The Homerton font does not have these characters.
EFF, a third-party supplier of RISC OS outline
fonts, has a different, but similar character
set.
