Indeed the result is strange.  Have you tried running bogofilter with
"-vvv" flags?  That will list the tokens parsed by bogofilter along
with their spam scores.  The FAQ describes the use of "-v" flags and
the output generated.

A message can be zipped and attached to avoid latin/non-latin issues.

Yes.  Bogofilter is a program and can only use the information you
provide for it.
