Abstract
Characters are generally represented on standard keyboards by the use of coding schemes such as ASCII and Unicode
but some characters of the Yorùbá language were not captured because of the accent and diacritic signs inherent in Yorùbá
language. Coding representation for Yorùbá characters has become a key problem in circuit implementations of keyboards for
typing Yorùbá documents correctly. The standard keyboard layouts do not have a simple key combination for all the characters.
To represent Yorùbá characters in human-computer interaction, this paper proposes the use of Unicode for the deployment of
Yorùbá keyboard for effective and efficient typing of documents in Yorùbá language. The approach used for the development of
the Yorùbá keyboard uses both binary and hexadecimal representation of the coding standards to codify Yorùbá characters with
their diacritic signs and the under dot. This dimension introduces the complex Yorùbá character coding representations using a
single code point standard. The generated Unicode point was transformed into HTML entities. The HTML entities generated
were converted to its character equivalent for the Yorùbá keyboard. The new Unicode was compared with the results of the two
encoding standard scheme using the bit relationships of upper and lower case characters to ascertain conformity of the new
Unicode with the standard encoding scheme. This provided some insights about the efficient representation of Yorùbá character
scheme. The representation is expected to quickly identify solutions to the design of Yorùbá keyboards and signage.
