carriage returns

[Tony Laszlo <laszlo@example.com>]

I use jvim and yudit for editing Japanese documents. 
I am having trouble with long strings of Japanese 
text which have no carriage returns. With Yudit, 
one has to go chase the data for several kilometers 
off to the right of the screen and with jvim, the 
data shows up as incomprehensible "@@@@" until you 
scroll down. 

I think it might be better if I were to insert 
carriage returns into such data, so that it would 
be manageable. But I don't know how to do that and 
suspect it might not be so easy due to the mixed 
double-byte/single-byte text in Japanese documents. 
Any hints on how this cat might best be skinned 
would be most appreciated. 

(I would like to stay with the apps I have now, if 
possible). 

Thanks.
