I just wanted to report a bug, and info-en(a)wikipedia.org referred me here. Sadly, upon trying to create a pdf (using the otherwise genius Print/export feature) of a page that involves lines above letters (e.g. http://en.wikipedia.org/wiki/List_of_mesons) the lines above letters (here essential to indicate the difference between Particle and Antiparticle) just disappear. In the linked Article that can be seen in the caption under the first Image where the pdf then contains the text "The strange antiquark (s)" despite there being a line above the "s" in the online Article. greetings, Daniel
