Sinhala language software for computers have been present since the late 1980s  (Samanala written in C) but no standard character representation system was put in place which resulted in proprietary character representation systems and fonts.

A lay person named Jayantha de Silva developed two HP PCL Sinhala fonts called Lihil and an intelligent Phonetic keyboard that was able to select letters based on context, together with a printer driver and screen fonts. All this was possible because the utilities to create the keyboard and printer driver were supplied with WordPerfect. It was easy to use and was installed in many PCs owned by lay members and in the temple PC for typing articles. The program fell into disuse after Windows came online in 1990 as it did not support the WordPerfect macro keyboard.
