Historically, the vowel pairs with ' were originally written without
it, and you simply had to know that "ai" was a diphthong and "eu"
was two separate vowels. The current Lojban opposition between
"ai" and "a'i" did not (does not, in Institute Loglan) exist.

Morphologically, "h" would suggest a consonant, but ' works more like
a diacritic on a vowel-pair, like the French trema.
