thanks for the reply.  Can you tell me what happens to the glyphitem and
the gi when I make that split?

The following code goes through a text line by line, run by run, and
glyphitem by glyphitem.  It then tries to split off the first cluster
and continue in the loop.

Line 79 is where the split happens.   I'm sure this changes the
glyphitemiter somehow, but don't know how to do it so that I can
continue inside that loop.   Any suggestions?

I couldn't find anything that is doing something similar to what I want.

any help would be appreciated.

many thanks -august.
