Block from U+0B00 to U+0B7F. This block was introduced in Unicode version 1.1 (1993). It contains 90 codepoints.
The Wikipedia provides the following information on block Oriya:
Oriya is a Unicode block containing characters for the Oriya, Khondi, and Santali languages of Orissa state, India. In its original incarnation, the code points U+0B01..U+0B4D were a direct copy of the Oriya characters A1-ED from the 1988 ISCII standard. The Devanagari, Bengali, Gurmukhi, Gujarati, Tamil, Telugu, Kannada, and Malayalam blocks were similarly all based on their ISCII encodings.
