# except that that does not mention an implicit vowel, so we use ọ
|

#
|
||
# 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!
