Six fraction signs historically used in Oriya have been included in
Unicode 6.0. These characters appear in written and printed documents,
and were part of at least four different sets of Oriya metal fonts.
The fraction signs were commonly used until 1958, at which time the
Government of India adopted the decimal system for currency and the
metric system for weights and measures. The characters are now obsolete.
The fraction signs are illustrated by R. J. Grundy in the Concise Oriya-English Dictionary
(Cuttack: Orissa Mission Press, 1928):
Amos Sutton shows only the quarter fractions in the Introductory Grammar of the Oriya
Language (Cuttack: Baptist Mission Press, 1831):
These fraction signs are now part of the Oriya block in Unicode:
The Oriya fractions are related to the ‘currency numerator’ signs used
in Bengali for writing fractions:
More information on the Oriya fraction signs is available in the
original proposal to encode these signs.
