Thanks Karsten, I am a bit new to this so I do apologize. Here is a link
to one of the offending emails,
When I try to have the Bayesian filter learn from spam in the terminal and
was to run "sa-learn --spam RANDOM_SPAM_MESSAGE" it would output as:

"Learned tokens from 1 message(s) (1 message(s) examined)"

However with the spam from (炉`路._..babes_in_blue^(TM).._.路麓炉) it outputs:

"Learned tokens from 0 message(s) (0 message(s) examined)"

Which leads me to believe it is not even recognizing the input as a mail
message so something is causing it to quit prematurely. My first hunch was
that something to to with the characters in the Subject line might have
something to do with it, because the characters "(炉`路._." and
"^(TM).._.路麓炉)" show up garbled in emacs or a similar reader.
