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
