Change a character of former dishonesty (6)
I believe the answer is:
reform
'change' is the definition.
(reform is a kind of change)
'a character of former dishonesty' is the wordplay.
'former' can be anagrammed to 'REFORM'.
However, I'm unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for reform that I've seen before include "Change one's ways (for the better?)" , "Go straight" , "Correct(ion of) abuses" , "Mend one's ways" , "Abandon evil practices" .)
