About scripts
The different languages on your computer are supported by software known
as the
script system. A script system makes a character set available for a
particular language, tells your computer which characters to display when you
type, specifies the direction of text flow, and provides other information such
as sort order, date, time, number, and currency formats. If you are working in
English on your computer, your system uses the Roman script.
If you are working in an Indian language, your system uses one of the Indian
scripts provided by this kit. The script system generates the complex
combinations of characters used in Indian languages in response to different
sequences of keystrokes.
For example:
The same script can be used by several languages if they share most of the
same characters and behaviors. For instance, the Roman script is used for
English, French, German, Spanish, and Italian. Similarly, Devanagari is used
for Sanskrit, Hindi, Marathi, and Nepali.
