Charlie — hurting no one, appealing to no one? (9)
I believe the answer is:
charmless
'appealing to no one?' is the definition.
(charm can mean attraction or appeal)
'charlie hurting no one' is the wordplay.
'charlie' becomes 'c' (phonetic alphabet: alpha, bravo, charlie etc.).
'hurting no one' becomes 'harmless' (doing no harm).
'c'+'harmless'='CHARMLESS'
(Other definitions for charmless that I've seen before include "not winning" , "Without attractive features" , "Lacking any appeal" , "Unattractive" .)
