I understand that completely! I don't expect you to put aside what you're
doing to look into the Unicode issue. There are a lot of people who need SWORD
who don't need Unicode. I am reading through the Unicode standard now and
experimenting with different options. If there is anyone on this list who is a
Unicode expert, I'd really appreciate some help in understanding some of the
issues involved.

I realize that SWORD is quite modular, however, since there would be very
little code shared between the ASCII portion of SWORD and any Unicode
extensions, I'm not sure that adding to SWORD would be the best option.
Besides Java provides some very compelling reasons to use it for Unicode
support. I was playing around with a Java Swing demo program today and I
inserted some Hebrew characters into an English text string. Not only did it
display them but it got the right to left order correct without me having to do
anything. Java has a lot of things like that built in that would need to be
done manually in C++.

Great. I'm not interested in forging out on my own even if a program seperate
from SWORD/BibleTime is needed.

Great! I'll take a look at that. That could a great thing to start from.

Thanks for the input.
