I'm trying to write a function that will return the name of a
epsilon etc. I was hoping this could be done
by extracting it from the second group in the following regexp
(in a function that determines whether a character is a Greek vowel),
but I don't know how, if at all, that is possible.
(defun greek-vowel-p (l) (eql (string-match "GREEK \\(SMALL\\|CAPITAL\\) LETTER \ \\(ALPHA\\|EPSILON\\|ETA\\|IOTA\\|OMICRON\\|UPSILON\\|OMEGA\\|RHO\\)" (get-char-code-property l 'name)) 0))
