Wrote a few tests to attempt IPA transcription

The rule for ui seems to be that it's usually hiatus (i.e., two vowels), as in fuit [fuit]. But note a few exceptions:

• when preceded by q the rule that gives us [kw] applies first.
• cui: [kuj]
• cuius: [kujjus]

To your other question, if you have two adjacent (orthographic) vowels and one of them is long, they do not form a diphthong, as far as I know. So your rules for handling diphthongs should only target short vowels.

For cui and cuius I'd add a special rule for them and no other words. Here are all the ones I know of:

# Lexical exceptions, mostly involving unproductive glide formation.
# All the below are undeclinable, except for <boum>, which only has an
# exceptional nominal oblique (the other forms of the paradigm are regular in
# the relevant sense).
# <ei>.
dein    dẽːj
deinde  dẽːjde
deinceps    dẽːjkeps
ei  ej
hei hej
# <eu>.
heus    hews
ceu kew
neu new
seu sew
ēheu    eːhew
# <ou>.
boum    bowũː
prout   prowt
# <ui>.
hui huj
huic    hujk
cui kuj
cuius   kujjus

I don't remember what my source was for this, sadly.

Should we close this in favor of #9?

Sure, sounds good.
