pdftk was built with a very old iText version that didn't support, at
the time, substitution fonts. See the thread
http://thread.gmane.org/gmane.comp.java.lib.itext.general/39983/.

thx, seems to be itext is a java library, not an end user tool, so the
only way is write a java application
have you any recomendation how to use it whitout java (in python)?
You can use jython or iron python.
Paulo
thx, I tried write a java application with itext, it works good
jython sounds good
