Indian Script Code For Information Interchange

Indian Script Code For Information Interchange

Indian Standard Code for Information Interchange (ISCII) is a coding scheme for representing various writing systems of India. It encodes the main Indic scripts and a Roman transliteration. The supported scripts are: Assamese, Bengali (Bengla), Devanagari, Gujarati, Gurmukhi, Kannada, Malayalam, Oriya, Tamil, and Telugu. ISCII does not encode the writing systems of India based on Arabic, but its writing system switching codes nonetheless provide for Kashmiri, Sindhi, Urdu, Persian, Pashto and Arabic. The Arabic-based writing systems were subsequently encoded in the PASCII encoding.

The Brahmi-derived writing systems are mostly rather similar in structure, but have different letter shapes. So ISCII encodes letters with the same phonetic value at the same codepoint, overlaying the various scripts. For example, the ISCII codes 0xB3 0xDB represent . This will be rendered as कि in Devanagari, as ਕਿ in Gurmukhi, and as கி in Tamil. The writing system can be selected in rich text by markup or in plain text by means of the ATR code described below.

One motivation for the use of a single encoding is the idea that it will allow easy transliteration from one writing system to another. However, there are enough incompatibilities that this is not really a practical idea. See About ISCII.

ISCII is an 8-bit encoding. The lower 128 codepoints are plain ASCII, the upper 128 codepoints are ISCII-specific. In addition to the codepoints representing characters, ISCII makes use of a codepoint with mnemonic ATR that indicates that the following byte contains one of two kinds of information. One set of values changes the writing system until the next writing system indicator or end-of-line. Another set of values select display modes such as bold and italic. ISCII does not provide a means of indicating the default writing system.

ISCII has not been widely used outside of certain government institutions and has now been rendered largely obsolete by Unicode. Unicode uses a separate block for each Indic writing system, and largely preserves the ISCII layout within each block.

Famous quotes containing the words indian, script, code, information and/or interchange:

    Music is so much a part of their daily lives that if an Indian visits another reservation one of the first questions asked on his return is: “What new songs did you learn?”
    —Federal Writers’ Project Of The Wor, U.S. public relief program (1935-1943)

    ...he sent letters to all the royal provinces, to every province in its own script and to every people in its own language, declaring that every man should be master in his own house.
    Bible: Hebrew, Esther 1:22.

    King Ahasuerus, after his Queen Vashti refused to come at the king’s command.

    Motion or change, and identity or rest, are the first and second secrets of nature: Motion and Rest. The whole code of her laws may be written on the thumbnail, or the signet of a ring.
    Ralph Waldo Emerson (1803–1882)

    But while ignorance can make you insensitive, familiarity can also numb. Entering the second half-century of an information age, our cumulative knowledge has changed the level of what appalls, what stuns, what shocks.
    Anna Quindlen (b. 1952)

    The press and politicians. A delicate relationship. Too close, and danger ensues. Too far apart and democracy itself cannot function without the essential exchange of information. Creative leaks, a discreet lunch, interchange in the Lobby, the art of the unattributable telephone call, late at night.
    Howard Brenton (b. 1942)
