* 符号化文字集合

[2] [[96図形文字集合]]を1つ規定しているのだが、次の[[用字系]]にまとめて対応している優れもの。
(各用字系の対応している文字を同じ[[符号位置]]に当てている。
一つの源から分化した[[印度系諸文字]]だから成せる業。)
-Devanagari
-Bengali
-Telegu
-Tamil
-Gujarati
-Kannada
-Malayalam
-Oriya
-Punjabi (Gurmukhi)
-Assamese
-Bengali
-Meitei

[10] 特殊な文字:

- [11] 0xEF ATR (Attribute Code)
-- [14] 次の1 [[印字可能ASCII文字]] ([ [N[0x20]], [N[0x7E]] ] ?) が引数
-- [16] [[フォント]]属性の設定
--- [17] [[script]] の切り替えも含まれる
--- [19] 副作用で [[ltr]] / [[rtl]] の切り替えが起こり得る
- [12] 0xF0 EXT (Extension Code)
-- [15] 次の1 [[ISCII]] 文字が引数
- [13] 0xD9 INV (Consonant INVISIBLE)

[18] ATR と EXT は[[制御文字]]と言ってよかろう。

* 符号化方式

[6] 
[[ISO/IEC 2022]] の[[終端バイト]]は未登録。

-*-*-

[4] 
[CITE[Emacs]] ([CITE[Mule]])
が[[私用終端バイト]]で [DFN[[CODE[indian-is13194]]]] として[[デバナガリ文字]]に対応しています。

[224] なお [CITE[Emacs]] は[[インド系文字]]の表示のために
[[94[SUP[2]]集合]]として
[DFN[[CODE[indian-2-column]]]] (Indian 2 Column),
[DFN[[CODE[indian-1-column]]]] (Indian 1 Column)、
[[96[SUP[2]]集合]]として
[DFN[[CODE[indian-glyph]]]] (Indian glyph)
を実装しています。
[SEE[ [[Fp]] ]]


-*-*-

[5] 
[[Compound Text]] が [[extended segment]] で対応している。



* 実装

[31] [CITE@en-US[C-DAC: GIST - Products - GIST Card]], [TIME[2025-07-13T13:59:46.000Z]] <https://www.cdac.in/index.aspx?id=mlc_gist_gcard>


[32] >>31 [[DOS]] で [[ISCII]] を表示する[[ハードウェア]]。


[33] [CITE[Gist Multilingual Products]], [TIME[2025-07-13T14:01:29.000Z]] <https://karjat-cdac.tripod.com/shell.html#shell>

> GIST shell is the "software only" solution for character based MS-DOS applications, which makes it posslible to enter, store, display and print text in Indian Languages and English simultaneously. This innocation software enables you to use off-the -shelf application such as dBase, Lotus 1-2-3 etc. in any Indian Language.
>
Also, as the Indian languagge data in store in PC-ISCII format, alphabetic sorting order can be maintained. You can also use GIST Shell woth custom made application too. 

>GIST SDK is a software development tool for Indian language applications. Thios is a set of software components that enable developers to facilitates the use of Indian scripts. Unlike other solutions, the significant features of GIST SDK is that it enable the MS Windows 95/NT application to process ISCII data directly. ISCII enable alphabetic sorting, transliteration, data exchange and reusability in a uniform manner.
>GIST SDK uses ActiveX Technology from Microsoft and provides a seamless, transparent and self-conrained Indian Language layer. It is based on COM standards and can be used with any of the latest application development tool providing "OLE container" support.
