Iran System encoding is an 8-bitcharacter encoding scheme and was created byIran System corporation forPersian language support. This encoding was in use inIran inDOS-based programs. After the introduction of Microsoftcode page 1256, this encoding became obsolete. However, someWindows and DOS programs using this encoding are still in use and some Windows fonts with this encoding exist. Now most programs use code page 1256 orUnicode.

Character set

[edit]

Only the upper half (characters 0x80–0xFF) of this extended ASCII table differs fromcode page 437, the lower half (0x00–0x7F) being the same. This character set encodes distinct visual forms separately.
