Google Groups diddles with my unicode chars.
The unadulterated code can be found here:
http://xahlee.org/emacs/elisp_examples.html
--------------
am not sure what's the prob with google. Don't know if they are still
experimenting with unicode chars in posts or what. I often use U+00AB
and U+00BB (french double angle quotes, here: <<>>). But starting about
2007-09, google groups either deletes them, or replace them with <<
and >>, or botched the replacement lopsided. (and this transformation
apparantly took place before it is posted, so it's distributed to all
other places, not just a displaying issue on goople groups) This week
i also noticed that they replace my bullet char "*" by a asterisk "*".
i'll be using one of the chinese quotations "「」『』〈〉《》" for posting i
think. For the bullet i might use a start "★" or heart "♥".
