  abstract  = {We consider two related problems in this paper. Given an undeciphered
	alphabetic writing system or mono-alphabetic cipher, determine: (1) which of
	its letters are vowels and which are consonants; and (2) whether the writing
	system is a vocalic alphabet or an abjad.  We are able to show that a very
	simple spectral decomposition based on character co-occurrences provides nearly
	perfect performance with respect to answering both question types.},
