EDIT Writing
Hanunoo is written in columns from bottom to top, going from left to right. Traditionally, it is written on bamboo.

Hanunoo is a syllabic script, which means that a character is not just indicating a vowel but a whole syllable.
A character by itself is a vowel made up by a consonant spoken with an "a". The characters U+1732 (Hanunoo vowel sign I) and U+1733 (Hanunoo vowel sign U) are diacritics that indicate when the consonant is instead spoken with either an "e/i"-sound or a "o/u"-sound.
