Bug when shifting CJK string by 1 cell

[Egmont Koblinger]

Hi,

Please see the attached test case.

First, a string is printed that begins with 'x' and is followed by some CJK.
Later, its first character is replaced by another CJK and the whole
string is printed again.

Expected: string updates properly, shifting all existing CJK chars by
half of their width.

Actual: 'x' is replaced by a space, the rest doesn't move.

I'm using 5.9+20140118 as shipped by Ubuntu Trusty, fully UTF-8
environment.  Sorry if the bug has been fixed in the mean time.


Thanks,
egmont
