Issue
An explicit U+25CC DOTTED CIRCLE is deleted before all vowel signs, vowel modifiers, and final consonants. This is in addition to the gemination mark, which has already been reported as issue #2.
To reproduce, go to
https://lontar.eu/en/notes/encoding-orders-of-brahmic-scripts/index.html#Soyombo
and check the rows VOWEL_ABOVE, VOWEL_BELOW, VOWEL_POST, VOWEL_MOD_ABOVE, VOWEL_MOD_POST, CONS_FINAL_BELOW.
Expected result: Each mark in these rows should be attached to a dotted circle, as each one is prefixed in the text with U+25CC.
Observed result: Each mark is rendered without a dotted circle.
