Hi there,

Thanks for raising this issue.

I've replicated this problem using the user-font test case in cairo's
test suite. I did that as follows:

	cd cairo/test
	make cairo-test-suite
	CAIRO_TEST_TARGET=pdf ./cairo-test-suite user-font
	evince output/user-font.pdf.argb32.out.pdf

Then I selected the first line of text and pasted into emacs running in
gnome-terminal. What I got was:

	0eez... cairo user-font

instead of:

	geez... cairo-user-font

(That's actually an ASCII '0' instead of an ASCII 'g'.)

Does anyone with more knowledge of cairo's PDF backend and the user-font
support want to look closer to see if this is a bug in cairo, the test,
evince or elsewhere? Behdad? Adrian?

Thanks again for the report,

-Carl
