No, I think it's processing calls to ContextHandler.characters correctly.

I tried the following Java driver program, in an attempt to simulate what 
you're doing, but the space character I placed in an xsl:text element is 
being preserved.  I even went back to versions as old as Xalan-J 2.3.0, 
and the output was always correct.  Without a sample driver program that 
demonstrates the problem, I don't think I can help figure out what's going 
wrong.  Are you able to produce a stand-alone example?
