Rev fails to recognize Chinese

[Friedrich F. Grohmann]

I've been working with Macs for a number of years under systems ranging 
from 7.5 to 9.2. Much of my data is in Chinese and I've made extensive 
use of HC in the past. Since I just got one PowerBook G4 with Panther 
installed, I finally decided to begin migrating to Revolution. 

To my utter astonishment, however, I can't get Rev to find Chinese in a 
text field if the text has been copied into the field. It will duly 
recognize newly typed text but does not react if it has been pasted. 
Since this happens in the case of both OS 9 and OS X files and since 
AppleWorks 6 does not have the same problem I can not imagine that this 
has anything to do with fonts (which are anyway all Apple fonts). 

Why does pasted Chinese escape Revolution? I will be enormously grateful 
if one of the gurus on the list could enlighten me about the cause for 
this behaviour  and graciously point out a solution.
