Unconventional tough guy receives information on personal problem (8)
I believe the answer is:
bohemian
'unconventional' is the definition.
(similar in meaning)
'tough guy receives information on personal problem' is the wordplay.
'tough guy' becomes 'heman' (I've seen this before).
'receives' is an insertion indicator (inserted letters are received).
'information' becomes 'i' (common abbreviation for information).
'on' is a charade indicator (letters next to each other).
'personal problem' becomes 'bo' (informal abbreviation for body odour).
'heman' placed around 'i' is 'hemian'.
'hemian' after 'bo' is 'BOHEMIAN'.
(Other definitions for bohemian that I've seen before include "Artistic, unconventional" , "like Smetana?" , "of old country" , "Socially unconventional" , "Unconventional person" .)
