Hi,

I have been using org for technical documentation and that involves inserted code snippets.  The org to pdf export works great but I faced issues when exporting to html.

After some digging around, I figured that having fci-mode enabled on a LANG-mode-hook caused insertion of some strange unicode characters in the html converted version.

Full details are in my reddit post here: http://www.reddit.com/r/emacs/comments/2b5x5g/funny_characters_appended_at_new_line_to_source/

To fix this problem by adding the following code after the line (funcall lang-mode) in the org-html-fontify-code defun in ox-html.el.

(when (require 'fill-column-indicator nil 'noerror)
    (fci-mode -1))
