Hi all,
 
In vietnamese there are two main kinds of Unicode:
1. Unicode pre-compound: means each character encoded to 16bits
2. Unicode compound: each char is composed from two 16-bits.
So the problem is that, when I find a string not only in KPresenter but also in Koffice, We could't find both by unicode compound and unicode pre-compound.
 
Maybe Linux support Unicode compound.
 
Did anyone got this problem?
