With konsole I use Liberation Mono too, and running vim in konsole the display 
is corrupted, though the glyph is sometimes displayed.   Setting 
ambiwith=double improves things a bit, sometimes the display is correct.

I would consider this a konsole problem; I get the same trouble at the bash 
prompt if I run

echo "THUMBS UP SIGN (👍)1234"

then go back and edit the line; vim is not involved.

But it's really a fundamental limitation in vim; it really wants characters in 
single cells, with some limited hacks for double width characters.  I can't see 
this limitation changing.
