# follows-consonant-av-bv              A tone mark, THANTHAKHAT, NIKHAHIT can only follow a consonant, above-vowel or below-vowel
# follows-any-precedes-end             An abbreviation mark, PAIYANNOI cannot be at the beginning of the label and must end it

#
# The character sequence U+0E4D U+0E32 (above diacritic NIKHAHIT followed by a vowel
# SARA AA) is considered an independent code point; this in order to implement the
# context rule "follows-consonant-tone". In this way, this character sequence is
# consider an exception to the context rule "follows-consonant-av-bv".
