This looks rather like bug 152888.  Not sure if it should be counted as a dupe
though.

Apon reading 152888, it sounds very much like my own case. To add to 152888
comment #4, I copy/pasted the characters (bytes) as seen from my english viewing
persepective. As for the english pound and euro symbol, I can type them from the
keyboard, yet the filter fails when I run it.

If every email message (even spam mails) is compliant to RfC 2047, it'd be
relatively easy to fix this, but most spam mails use 'raw' octets with MSB set
(violating RFC 2047) in the mail header(Subject, From, etc), which makes it more
difficult than otherwise to fix this and bug 152888

I should have marked this as dupe of bug 152888. Reading it convinced me that
it's a dupe.
