So =9D is a zero-width non-joiner. With normalize_charset this can be
detected as the UTF-8 version seen before.

My understanding is that zero-width joiners and non-joiners go
between two characters to control how they are typeset, so presumably
they shouldn't be next to a space or punctuation mark.

Erm, thanks, but it's much preferable to upload the raw spample to 
someplace like pastebin and just post the link here. That way (1) the 
spample doesn't get quarantined or discarded from content scanning, and 
(2) the spample doesn't get modified in transit.
