Thank you for your help.
THE PROPOSED ADDITIONS:
1. Please add the following program to the end of lk symbols file
=PLEASE ADD AT BOTTOM OF symbols/lk FILE==
// SINGHALA - US, SUBSTITUTES SOME AND ADDS SOME
// =
//
// This started as an upgrade to the first romanized version of
// Singhala called PTS Pali created in the 1860s. PTS requires
// dots and bars on letters that are rare in fonts, and impossible
// to type. Its singular purpose was to print Tripitaka, the
// collection of Buddhist discourses.
//
// This version covers the entire newer Singhala phoneme chart
// (Hodiya) that became standard just before the end of the 19th
// century. All the phonemes map to the SBCS. It is easy and
// faster than English to type. It overcomes the setback of
// Unicode Sinhala that it is not compatible with Pali and
// Sanskrit because it encodes two ligatures as base letters and
// the SLS1134 specification matching shape and morpheme sets
// violating Sanskrit orthography.
//
// Most importantly, this romanized version of Singhala has a
// companion orthographic font that displays the text in the
// native script and a JavaScript converts it to Unicode Sinhala
// and back dramatically increasing Singhala seen on the web due
// to its ease of use
