In the second and third revisions of 1134, Sinhala encoding as well as to how Sinhala characters are stored on digital devices are given with the keyboard layout. The keyboard layout which was released for computer input was known as Wijesekera extended keyboard for Sinhala input. The committee which was responsible for designing of SLASCII decided to use the same layout of Wijesekera keyboard layout which was standardised for typewriters. In 1990, when SLASCII was released as the standard for storing of Sinhala characters, the keyboard for Sinhala character input was also decided in the first version of SLS 1134.
The previous part of this paper article ‘Introduction to Unicode Standard or Universal Encoding Standard’ had been already published in Daily FT.
