Iran System encoding standard

From Wikipedia, the free encyclopedia
Jump to: navigation, search

Iran System encoding standard was an 8-bit character encoding scheme and was created by Iran System corporation for Persian language support. This standard was in use in Iran in DOS-based programs and after introduction of Microsoft code page 1256 this standard became obsolete. However, some Windows 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 or Unicode.

Code page layout[edit]

Only the upper half (128–255) of the table is shown, the lower half (0–127) being plain ASCII. This character set encodes distinct visual forms separately.
