gnome-terminal displays "missing font" glyph very poorly

[Tv]

I was wondering why some of my log lines did not contain a final closing doublequote, if the quoted string contained some funky UTF-8. In fact, they did -- the quote glyph was just drawn in the same space as the "font missing" glyph.

Attaching a screenshot to demonstrate. Run

python -c "print u'\U000ffff0X <- the X is obscured'"

to see for yourself.

Only in my epc 900 the char u dislpayed as ' ' in gnome-terminal. No problem with xterm or any other apps or other computer or even other Ubuntu version.
