Description Christian Persch 2012-08-22 11:41:25 UTC 
Printing http://www.unicode.org/Public/6.2.0/charts/blocks/U25A0.pdf I got two

Internal Error: cairo context error: input string not valid UTF-8

errors on console. So it appears either evince or poppler is feeding invalid UTF-8 to cairo.

evince and poppler from Fedora 17.
