I've had good results scoring for the combination of windows-1256 encoding
and quoted-printable. It pushes some junk over the top into spam.
Admittedly a message that is mainly in a Latin character set with a quote
from Arabic could be so encoded, so I don't give it a killer score, just a
bump.

Pedro, I just checked a spample I have and it hits on the rule. Note, I do
not use normalize charset but just expanded the rule to allow for that
thanks to RW's post.

If not, do you have access to it? If so, please pastebin it.

detected as the UTF-8 version seen before.

Yeah, there is a SCC SHORT WORDS rule and a KAM_ZWNJ in KAM.cf. Please let
