What about diphthongs? Technically a diphthong is *one* vowel
made up of two letters. The rules vary by language; Spanish
even has triphthongs, e.g. in Raoul. A diphthong/triphthong
occurs wherever a succession of vowel symbols doesn't contain
a syllable break.

Perhaps this would be a good Ruby Quiz?
