Double the vowels, Punctuate the consonants .. raw:: html This scheme was originally developed in 1991 by Frans Velthuis for use with his devnag Devanagari font, designed for the TeX typesetting system. Pali and Sanskrit scholars have since adopted it as a standard technique in Internet correspondence. .. raw:: html In the Velthuis scheme, two basic rules are observed: .. raw:: html 1. Long vowels (those with a macron (bar) above them) are doubled: aa, ii, uu. .. raw:: html 2. For consonants, the diacritic mark precedes the letter it affects. Thus, the retroflex (cerebral) consonants (those with a dot underneath) are: .r .t .th .d .dh .n .m .s .l. The guttural nasals (m with a dot below or n with a dot above) are represented by "m and "n. The palatal nasal (n with a tilde) is ~n. .. raw:: html The scheme is precise, although it takes a while to get used to. Here is a table of the affected Pali letters in both unicode form and Velthuis scheme. .. raw:: html |
