[exim] Garbage Characters In Log

I have Exim logging message subjects in messages.

Most of the time there is no issue, but some messages are using who know
what type of encoding and I end up with what looks like trash in the
subjects.

T="SPAM: ���γɳΪӪŪЪ㪹�IJ�òŲֲ��ܲwphilbrick"

T="\033$B!Z4|4V8BDj!*%]%$%s%H\033(B10\033$BG\\\033(B\033$B!y![?)$NJu8K!Z6e=#![$N?):`$r87A*!*!V\033(B\033$BGnB?IgMV!W4F=$!*!VC"

Anyone know of a way to figure out what these subjects are?
