We are using Template Toolkit 2.19, which is the most recent version and 
we have used it quite extensively up until this point without any problems.

I narrowed the problem down a bit more to the use of the ENCODING 
option.  HTML::FormFu sets it to UTF-8 by default.  If I set it to 
undef, I do not experience the problem.

I'll let you know if I find out anything more, since I am continuing to 
debug it... thanks for the reply!
