Thanks for feedback.

After checking again about this behaviour:
There MUST be some unicode characters be involved in your environment and startup sequence.

The problem comes up at the edge between UTF-8 (Jython level) and UTF-16 (Java level) and according to the comments in the net is a common problem with implementations, that have to handle both worlds.
According to the spec, the unicode points  U+D800 to U+DFFF are invalid as single character (you always need 2 of them).
So it surely is some Jython bug, that cannot arise with Jython 2.5, since this does not handle unicode internally at all.

So this might be solved for you now, but I will turn it to a bug, to
watch it further.
