When opening a man page in yelp using

yelp man:rsync

yelp can't seem to parse the double quotes character.

see screenshot

steps to reproduce:

open a terminal (CTRL+ALT+T)
type: yelp man:rsync
scroll down to the second paragraph in the Description section
you'll see ? in black diamonds (�) instead of double quotes (").

then open the man page in another terminal
CTRL+ALT+T
type: man rsync
scroll to the same second paragraph in the Description section
low and behold double quotes "
