It would obviously help to see the content of the line mentioned in
the traceback (and probably its context);
however, that value seems to correspond with â in some European
encodings, in which case it would probably be part of some quoted
unicode/string literal. (at least in python 2, in python3 it could
also be a name of an object in python code, the traceback seems to be
the same for both cases.)
cf.
>>> print '\xe2'.decode("iso-8859-1")
â
# and likewise for iso-8859-... 1,2,3,4; 9, 10, 14, 15, 16, some
windows- encodings etc.

Possibly (as previouslz suggested) adding the encoding information
like iso-8859-1 or windows-1252 or others depending on other data etc.
at the top of the source file might fix the error. Which would be
certainly preferable to throwing all non ascii data away.
Zou would add e.g.
# -*- coding: iso-8859-1 -*-
as the first or second line of the file.
