The Wikipedia provides the following information on block Kannada:
Kannada is a Unicode block containing characters for the Kannada and Tulu languages. In its original incarnation, the code points U+0C82..U+0CCD were a direct copy of the Kannada characters A2-ED from the 1988 ISCII standard. The Devanagari, Bengali, Gurmukhi, Gujarati, Oriya, Tamil, Telugu, and Malayalam blocks were similarly all based on their ISCII encodings.
