Just had an hour-long battle with an exception to that rule!

I yanked from google/firefox and pasted a link into org-mode/emacs.
When exported to html that link was having some junk character(s) that was 
giving a broken link on being clicked.

Naturally my mind was going along the lines "bug in org exporter..."

Cut down the org file to a single header and the link. No luck

Switched from org to fundamental mode -- same -- no character in the link in 
emacs but some junk on html-export.

Finally switched to vi. It showed me:

between OOp and FP]]

200e??? What the hell...
Asked emacs to describe-char (the nothing at that point!) and that is something 
called 'left-to-right-mark'

So humble request: Please show what is there!

Emacs version 23.4.1
