# Thai-Latin
# This set of rules follows ISO 11940
#     see http://homepage.mac.com/sirbinks/pdf/Thai.r2.pdf
# except that that does not mention an implicit vowel, so we use o\u0323
#
# The transcription is fairly ugly, so we ought to also do the UNGEGN version
#     see: http://www.eki.ee/wgrs/rom1_th.pdf
# and probably make that the main variant.
#
# Note: this is an internal file. The NFD/NFC is handled externally, in the index
# The insertion of spaces between words, the reversal of the vowels
# and the conversion of space to semicolon are done *outside* of these rules.
# So as far as these rules are concerned, the vowels are in logical order!
# insert implicit vowel (and remove it going the other way)
# COMMENTED out: the implicit vowel positions cannot be predicted algorithmically
