// X Keyboard Extension file for Sinhala (Sri Lanka) (2004-04-22)

// This is a phonetic static mapping for a standard US-English keyboard
// (QWERTY)
// http://www.nongnu.org/sinhala/doc/keymaps/sinhala-keyboard_3.html

// Repaya, Rakaransaya and Yansaya aren't inserted with A-r, R and Y,
// respectively. The problem lies with the XKB infrastructure which
// only allows a one-to-one mapping of keycodes to Unicode codepoints.
// Unfortunately, the 3 mentioned glyphs actually consists of 3
// Unicode codepoints each. The result is that the user must
// manually construct the glyph by typing each of the 3 codepoints.
// ALT-, represents the 'JOIN' key, it requires
// two codepoints, hence it also has to be manually constructed.
// Similarly, ALT-/ representing the 'TOUCH' key requires
// two codepoints.

// Repaya = rayanna,AL,ZWJ
// Rakaransaya = AL,ZWJ,rayanna
// Yansaya = AL,ZWJ,yayanna
// JOIN = AL,ZWJ
// TOUCH = ZWJ,AL

// Where,
// AL = Al Lakuna = ALT-a
// ZWJ = Zero Width Joiner = ALT-/
// rayanna = r
// yayanna = y

// SINHALA - US, SUBSTITUTES SOME AND ADDS SOME
// =============================================
//
// This started as an upgrade to the first romanized version of
// Sinhala 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 Sinhala 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 Sinhala 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 Sinhala seen on the web due
// to its ease of use
