"""
All phonemes in the IPA standard are supported.
zero-width characters are generally not supported, as
well as some other modifiers. Tone, stress and
lengthening are represented with placeholder dimensions,
however they need to be set manually, this conversion
from phonemes to features works on a character by
character basis. In a few cases, the place of
articulation is approximated because only one phoneme
had such a combination, which does not warrant a new
dimension.
