After the changes you made the display looks good with
Bitstream Cyberbit and Clearlyu.  Don't know about the
left to right issue.  We will have to find someone that knows
one of those languages to test it.

YES !!!!!!!!!!!

This simplifies things greatly.

I think KDE sets helvetica as the default unicode font as now I sometimes get

(BibleTime 1.1beta2) WARNING: the unicode font found by KDE is helvetica

Usually when issuing a print request, however the helvetica installed only
seems to have the western european (plus German and possibly eastern
european) characters (no greek for example).

I think it did what KDE is doing after deleting bibletimerc

[fks00@localhost bibletime]$ bibletime

This is OK as long as I take this into account in the handbook.
Checking a font to determine if it has the characters needed to display a module
would be
painful the program would probably need to check it character by character, and
compare it with the contents of a module..

This message occurred when trying to start bibletime when the unicode font
selected in bibletimerc was a iso8859-1 font.

I tried to force the error, whatever you did seems to prevent the application
from
crashing; however the following is displayed if IGNT is opened and bitstream
courier
is the unicode font.

This is much better than crashing!!!!!!!!!!!!!!!!
